AIRGUN Repair – Power Increase – Tune / Tips + Tricks – Basic Guide PCP Air Rifle – Artemis M30, hello there welcome to the AG and gear show this one is a little bit different in front of me is the Artemis M 30 I saw this a couple of years ago and I’ve wanted to have a closer look at one ever since I’m interested because it has that barrel going through the air cylinder and it’s very different so I spent five hundred pounds of my money much to my wife’s annoyance and I bought one however things aren’t all rosy it’s got a few issues in fact it shoots like a dog a half-dead dog and its list of issues are longer than the excuse book from Harvey Weinstein so I’m kind of stuck what do I do with it now well I thought why not let’s turn it into a project a tuning project and I thought I’d do that and give you some tips and tricks of how you can improve your air rifle along the way [Music] this is a really good-looking gun on the bipod it is a really good presence I like the look of it and that’s one of the reasons that I went for it now obviously it’s got a few issues I don’t want to send it back even though I know that it would get fixed if I did send it back so as I said before I’ve decided to turn this into a bit of a project and a learning curve for me and hopefully something that will help you guys out as well now this is quite a technical shot to get all these close-up images that you’re gonna see I’m not capable of that with my camera I’m just not good at it so I’ve got Ben who’s filming me here who’s helping me out and we’ve got cameras over there and cameras on the ceiling and lights and all sorts of things lit up on the benches so Ben’s gonna help us out now the accuracy on the rifle before wasn’t good I mean we’re talking you know maybe a two inch size group at 20 yards I know that that can do a lot more than that however what I’m about to show you will let’s be very clear on this void your warranty if you take any gun apart and it’s still in that warranty period and you start making changes on it you’re going to void your warranty just to be absolutely clear if you take your gun apart and you mess it up you’re going to have to pay someone to put it back right for you either the manufacturer or a specialist so I am NOT encouraging you to do this at all in any way shape or form so if it goes wrong it’s your fault and you’re the idiot for watching me do this safety it’s very important you’re working with a gun obviously you want to make sure that there’s no ammunition around whatsoever that’s always a good start but always always be mindful that things could go wrong make sure you’ve got lots of safety equipment with you you’re working with high pressure air as well which we’re going to clear right at the start but please be aware high pressure air if it goes wrong can cause injury and harm so if you’re a junior or someone that’s not too sure what they’re doing don’t do it get an adult to help you or just don’t do it I’ve been practicing this for nearly a week now in the evenings I’ve been taking this apart learning how it goes back together and I’m also learning where the errors are in the rifle so this is not a quick fix I’m not showing you how to quickly repair something in two seconds this is something that you’re going to need to take time with and a little bit of patience enough of me gobbling on let’s get started I’ve got a three mil allen key and I’m going to remove the scope now you would normally probably undo all the screws on the top and take your time I’m just doing it a bit of a cheat way just to get us started okay I’m just going to talk to you about the stock here you will notice that over my last week of battling with the gun I’ve had to make some changes already just to get anywhere so basically I’ve had to sand down this part here because when the bolt comes back it was actually rubbing against the outside of the stock which is you know a bad fitment so you will see that on the stock at this time I’ve sanded this bit out already but I’m gonna have to take a bit off here because as you can see when I flip the bolt up can you see the grease mark there where the stock is rubbing against that and you can actually see the action yeah look what you got to remember is that if you deflect here because this is quite a loose fit here right if you deflect here it’s going to eventually move that probe when you push in the pellet in each time look look so again I gotta sand some more off there now I’m not gonna lie to you I’m having to sonned bits off the stock to get the bolt to pull cleanly in and out it’s really quite annoying when I’ve spent five hundred pounds on this you can see here where I’m getting residue and build-up where the bolt is rubbing against the stock there and that feels now oh look at that that’s different yeah look next we’re gonna take the stock off the bottom I’m leaving that on there because that’s going to help the stock stand up afterwards so again 3mm allen key and we’re gonna undo this screw here and then there is one just a little lower down here on the trigger guard that’s a three as well and then we need a Phillips to undo the trigger guard at the back just there this bit won’t come out through the trigger guard unless you take the trigger guard off trigger guard off then what we’re going to do is we’re going to separate the action from the stock very carefully just like that the gun itself is still charged it’s still full of air so we need to get that air out this is probably one of the most nerve-wracking parts of doing the whole thing because you’re gonna get a lot of hissing and you’re gonna let the air pressure out now this rifle you can let the air out in two ways it has a screw on the top which i think is actually part of the manufacturing process but I could be wrong and when I undo that the air will escape from your cylinder or I can undo this gauge here at the front which is the air reservoir gauge and that won’t bleed the air out now I would like to point out to you I am NOT a gunsmith in any way shape or form so I’m trying to do this as safely as possible so please please please when you’re working with high pressure air be careful and don’t expect anything to go wrong but let’s just put some safety goggles on just in case now I’m using a 3/4 inch spanner and I’m gonna undo the gauge at the front which is going to let some air out a little simply just gonna let that lead out for a minute with these rifles and these o-rings that are on there once you start a bleed-out process I wouldn’t then stop it because if Ben can come round and just capture this bit here for me you can see that the pressure is pushing the o-ring out just there the little brown bit there so that will seat back okay in a minute but if I was to tighten that back up now I would crush that oring and cause a problem so I’m just gonna let a little bit more out we go just there and you can see that a ring now I think that a ring has got a little bit pink so it may not have survived but the good thing is they do give you plenty of earrings in the kit to change if you need to if you need to take the air out of the system on a high-end rifle like this impact all you do is unscrew the air cylinder so I’m not gonna take it all the way off now but you can unscrew that air cylinder and maybe drive for a couple of shots and you’re completely clear of air so that’s the difference on a budget rifle like that what you’ve got to do is you’ve got to manually bleed all the air out but on a high-end rifle you just unscrew the bottle so think just here okay just give it a wiggle but it’s it’s finger loose now which means basically we’re good and obviously it’s not hissing and as we take that out Oh lost a little bit of residual air just always be careful as we take that out you can see where that a ring has become damaged by doing that now I’ve done this sort of I don’t know ten times I suppose in the last week so this o-ring has taken quite a lot of battering so I wouldn’t expect that to happen every single time but obviously it’s happened this time so there’s your pressure gauge we’re going to put that over there and we’ll change the o-ring in a minute we may as well now while we’re here just undo the regulator gauge no error in the system look and when that comes out the o-ring is in good condition now on some guns you may find that you need to undo the regulator gage and it does hiss a little bit or whatever so you do get variables depending on what you’re doing but if you drain the system totally you shouldn’t get too much of a hiss on this gun and it’s only particular to this gun from what I’ve seen there is a screw thread on the top just there look and if the gun still had air in it you can undo that and that pops off with a little o-ring there look and you would get all the air coming out now you don’t undo it sort of part of the way until it started to hiss like the gauge below and you see the o-ring pop out the sides and you you have to expel all the air before you tighten it back up I think that’s probably a hole that’s left over from the manufacturing process and that’s the only way they’ve decided to plug it and it is only from you know what I’ve seen on this rifle but it’s that so I need to cover it think the dangerous bit is over so I’m going to take the goggles off the next thing I’m going to do is remove the hammer spring and that’s down here so I’m using a flathead screwdriver I’m simply undoing this here like that the guns not cocked so there may be a little bit of tension in the spring but not a huge amount so that comes off there we go like that and then we can just remove the hammer spring some guns the layout inside will be different but on this one that’s basically how it is there’s a slider screw on the side of the hammer itself using a three mil allen I’m just going to undo that like that okay and then just very carefully you can will need just a little bit of a push to get it going there’s my watch pinging I’m going to push that out now when you do that what happens is is the Sears on the trigger have pushed up it’s be honest sometimes it does it sometimes it doesn’t but I’ve done it that way I could have removed the trigger first but what I’ve done is I’ve taken the hammer spring out first because if I remove the Sears it stops everything projecting that way it’s all under tension so whichever way you do it you’re going to get a pop if you take the springs off first in the Sears they’re all spring loaded and they’re tiny and if it flies that way you’ve got a problem so taking that out I’ve removed the tension first there’s the hammer so the hammer spring would be in there like that and then that goes in there like that and I will see you’ve got that action going on now when I first got the gun this was back it was completely gone it was a huge mess and I mean this whole chamber where the hammer spring was was just completely full of tractor grease you couldn’t you know you couldn’t see anything silver on there at all so what I’ve done is I’ve I’ve taken this out it’s got tiny little bits silicon grease on there now but what I learn is I’ve taken this out I’ve cleaned it degreased it polished it up made it all nice and clean and smooth so that when it’s inside that chamber there where the hammer spring runs it’s running a lot smoother it’s not perfect but it’s a lot smoother and it’s certainly not full of tons of grease causing all sorts of issues also this little screw on the side here this looks like a a scope mount screw which is when I got it it had like almost semi serrated edges so what I’ve done is I’ve shined the screw up because obviously that runs inside the chamber to retain the hammer and it was just grinding on the inside of the chamber so what I’ve done is I’ve rounded it cleaned it up so now it runs really smoothly and that’s made a big difference next thing I’m going to do is I’m going to remove the trigger system now listen to me this is specifically laid out in a very specific way within the gun so if you just go and remove these pins and it flies out everywhere you ain’t going to have a clue where the bits go back and there’s my phone again telling me that I should be doing more exercise but basically what you need to do is take lots and lots of pictures of this as you go you all got camera phones but make make a reference as to how its laid out take a look and say well you know where does that little spring go in there how does that spring sit if I flip it over and try and show Ben you’ll see that there is a tiny little spring just inside there camera may not see it you’ll see it in a minute so when you when you do that you know pay attention to what’s going on and to where the seers are sitting and how you’ve got it set take some pictures write something down draw something because when we put the gun back together that bit there is the most frustrating that bit has nearly made me cry several times during the week I’ve got the hang of it now but it’s taken a lot of times to practice so pictures take some reference I’ll say I’ll give you some pictures in a minute but record how it looks what I’m using is a very small sort of punch it’s a 1.6 million as well it’s going to ruin the tip of my bridle but I’m going to use it and a very small pin hammer and all I’m doing with the gun supported is I’m literally just going to tap that pin through like that and then you’ll see on the underside the pin is starting to come out now what will happen is is that the punch will only go so far so then I use the Brazel just to get it going and to keep it coming out now some of them will just fall out because once the tension is released this one at the back will just fall out the first one is the one that’s normally under the most tension and when this drops in a minute I’m trying to pull it this will spring forward so you’re gonna need to keep your eyes for Springs that may move there we go I’m trying to do it gently so let’s see how far that pin is out OOP maybe just a little bit more right now you know while I’ve got that there Ben can have a look can you see that tiny tiny little torsion spring just in there a tiny tiny spring if the camera can focus on it so just you know remember where that is and how its situated because it is kind of important okay so I’m then going to take the Bradl out and then there’s that tiny spring look as you can see I’ve tried to keep it in place and that’s kind of how it is when it goes back in with that pin going through it like that okay so there’s that bit then there’s any which way you can do it now this one at the back will probably just fall out there it goes I’m only tapping that by hand pull it through and Ernie and that one’s out that’s a bigger pin then we’ve got these ones here there’s still a little bit of pressure on them so they don’t need much more they again it’s a lot easier and then I can remove that by fingered you see that all popped out then I’ll either sort out for you in a minute so you can see how it goes take these out here comes out there and this one is flown out inside but I’ll demonstrate that to you in a minute then we’ve got this see remaining give this one a tap at the top that should pull out at the bottom now it’s a little stiff so I’m just going to use my Brattle just to help release that one there it goes now and it pops this bit should then come out there we go another part of the sear which I will show to you in a moment and then finally there is the hammer say which is still inside but because we took this big pin out it’s loose so it’s either going to fall out there or fall out inside let’s see where it comes to just give it the tap there it goes and it’s fun out onto the table so what you’ve got here this is the hammer spring with the hammer that moves and it slides against this hammer spring sort of retaining bar here and when you cock the gun what it does is it slides back like that oh and it drops behind that little Ridge there in there like that and this all tensions up because that’s pushing down there then what happens is is that when you pull the trigger it moves all these seers and this basically comes down I push it down like that and this then flies forward and strikes the valve there you go so that is in there the basic layout of how the trigger is but there are different layouts for different triggers in different guns next I’m going to want to try and take the bolt out just here now this bolt is retained in by this allen screw here it’s as simple as that so what I’m going to do is I’m going to go at it from the inside just there now something to learn with this rifle and it’s loose again because there was no pressure on that at all is that this screw comes loose after about 20 or 30 shots so and it’s all dropped off inside you are going to want to put when you finally got your rifle set how you want you’re going to want to put some thread lock on that to help it stay gonna tip and that screw should there it is fall out that and then what will happen is is this will just slide out like that now if deliberately left that in there to show you in a moment but can you see that scarring I put that down on top there this scarring line just here and there is a little bit of silicon grease I’ve been using that’s caused by this pin here which I’ll take out in a moment and that pin is just poor quality so it stops the bolt flipping on firing at that and this rifle does that the bolt does flip and the way they’ve got round it is just by putting that Allen screw in with like a rounded head on the bottom that spring loaded it really needs to be like a ball bearing or something like that that’s free-floating on a spring so the only way you can stop the flip is when you fire is to tighten that up but then when you pull that back its scars on the bolt you see and it’s in this position so I would suggest that maybe change that out to a free-floating spring and ball bearing or you’ve just got to accept that that’s what’s going to happen to the rifle but let’s take that bit out now you can see that it’s a ball bearing but it’s not rotating it’s just on a like a fixed spring look so if I find something a little bit firmer than my fingernail to push in it does sort of spring load as you can see but in no way does it rotate so what it does is it scars the bolt and I think that could be swapped out but there we go before I forget we’ll take this bit off you don’t really have to it’s just part of the trigger mechanism that holds the spring at the back there we go next we’re going to remove because we’re still in this position the regulator now be gentle I mean be gentle this is a a core part of the gun and when you take it apart you need to take it apart gently so that when it comes out it doesn’t fall apart in your fingers because you’re going to struggle getting it back together otherwise but basically I’ve got a 9/16 which as I’m much of an engineer I am little spanner and I’m simply gonna undo this here like this and we’re taking the rag off there it goes and we’re taking the rag off now because we can’t get the valve out inside until we’ve taken the rag off and you’ll see why in a moment and I’m being gentle with it trying to use my fingers where I can because I don’t want to force anything this is full of a rings inside so when you start to feel tension just go gently you don’t want to damage those o-rings even though there are plenty of spares you don’t want to damage them and what you’ll find is that when it starts to feel like you’re not actually working against a thread anymore and like it’s just rotating or it’s not actually coming out any further you can start to see if it will take a little bit of a wiggle that you see and as I’m wiggling that over there it goes as I’m wiggling that ring now I’ve got it to that position and what I’m going to do is so that when I lift it out it doesn’t all fall apart I’m going to sort of turn it on its side enough a bit and I’m just resting on an o-ring so I’m ever so gently giving it a wiggle and a turn so we don’t want to damage it it is all about patience all about patience ok so there’s the bottom of the rag and inside is the top now I’m going to use a pair of long nosed pliers but there is an o-ring just in there so don’t put this in and rag at it as hard as you can it is a gentle persuasion gentle Rajon just to get it to pop like that and you can see that a ring and then what you do is you’re gonna get your fingers and rotate the gun so that all those washers and springs don’t come off okay it’s gentle gentle because you want to keep those in order there is it was that last a ring on the top look that’s holding it in so then there it’s the top off your regulator to just try and hold it all together I’m just gonna turn it round and just put them together like that now keep this clean keep it super clean you don’t want dirt in there there is some grease in there look just a small amount just to help it move on the o-rings but keep this clean so we’re going to remove sorry sorry I started before Ben set action sorry man okay so basically what we’re gonna do now is we’re gonna remove the valve inside and this does take a little bit of playing with and you’re gonna need your punch again and the valve if I can show you is in there and you can see there the head of the valve which is what the hammer strikes we can’t get that out without removing the regulator and the regulator gauge because we need to be able to poke in there just to give it a little bit of a nudge forward also while we’re doing that I don’t want to bang or work against the regulator or the thread or anything like that with at all which is why I’ve removed the regulator but we’re going to need our punch because we’re going to knock out these two pins here that retain that valve there’s no air pressure behind it so they’re partway through and then I’m gonna get my Bradl which is my GT tool and you’ve got to expect that you’re gonna ruin your Brattle during this there’s one’s dropped out just there let’s see oh my let’s move out the way on my clean workbench I’m a very messy worker always been a messy worker and then we’re just gonna tap that one out there there we go so we then got the two retaining pins out now when we’re doing this like I say we are working close to the rag which is why I wanted the regulator out first before we do anything now that valve because it’s under a spring at the back here has moved forward just a little bit but what we want to do is sort of poke it forward now you don’t want to get anything in there and grab that valve stem because we don’t want to scratch the valve stem which is this bit in here we want to do is just give it a nudge forward so this is from experience I take a little 2.5 but the camera can see it in there is the back end of the valve spring I’m going to pop that in there and you know ever so gently just try and catch that spring and push it downwards right a little bit more because then the vowel was got a cut out where the rods go on it and we can get it there we go and we’re looking for that gold evolve with the cutaway see it you got it and what we’re gonna do is just gonna take a flathead screwdriver and we’re just gonna gently ask it to move down and it’s got two earrings on there so you really don’t want to go smashing this about very gently slide it forward there is and it jolted because it hit the end of here and then out it comes and you can see look these are my screwdriver marks from the weeks come by where I’ve been putting this thing in and out so out comes the valve there is a spring in there which is going to fall out that’s it and that spring goes on the other end of that valve so when the hammer flies forward when you’ve pulled the trigger nope it hits that valve really quickly and what happens is it’s this then flies open and a squirt of air goes through there up out this hole and into the gun and projects the palette forward now this valve stem is super important when I got mine in the original gun this was all filthy all of this was filthy this was filthy I’ve polished it all up and cleaned it all up this was all filthy and the valve stem itself was just black and corroded and when you’re actually moving it through here it was sticking but now it moves you know like a hot knife through butter which is lovely so that’s super important so everything needs to be cleaned and tidied and me cleaning that and polishing that up and getting it set right and cleaning all that out has noticeably made a difference in the consistency of the rifle and in its accuracy to be honest so that’s a super important bit so we’re just going to keep cracking on so what going to do is because the gun is still in a good way to hold with the Barrel on we’re going to just pop these off which are four screws here and I’m going to find the right size tool and that’s a three and there’s four of these Allen screws to undo now it takes a couple of minutes to get these off so I’m sure Ben will use some sort of miracle of technology but and I deliberately haven’t cleaned these over the last few days because I want you to see what condition they’re in there it is okay and you can see the two screws below which is sort of touched right before we look at that bit let’s talk about these screws because they’re all in the same condition rusty you see that that’s not I don’t think that’s retaining fluid doesn’t look like any sort of thread lock that to me looks like rust from old screws and that means that you know the quality control of the build of the rifle when you’ve got this which is the fill valve is you know those should be beautifully clean so here we go so here’s your fill valve fill probe goes in there it goes under pressure and then this o-ring and this o-ring here helps to fill the rifle up now we could take that all apart but I’m not going to because they’re notoriously once you’ve done it you’ve had it sort of things so unless that oring fails on you I really really really wouldn’t touch that so I’m just going to leave that in situ but that’s basically fill valve but if it goes wrong it’s normally that one there all that one there that you’ll need to replace I’m not pulling that apart today we’re finally going to take the barrel off and the air cylinder now on the front here you can see that there’s this section that is the that is the silencer in there and you can access the silencer by unscrewing this cap on the top like that and that will come out and then all the silencer bits will fall out we don’t wanna do that today there’s no need to do that today but we have to separate the silencer part from the barrel because this silencer housing is critical in holding all this together so I’m unscrewing this section here as you can see rather than the top section now this is a revolutionary revolutionary I don’t know some people have done it before I suppose way of doing it and there is what I think is a critical downfall in here oh there we go now the Rings popped out already what I’m going to do is I’m gonna just give that a wiggle and it’s not going to play ball with me it’s come loose at this end already so I’m gonna just keep twisting in fact it’s completely not play ball with me that bit should pop off I don’t want to force it from this end so what I’m going to do is I’m going to undo this end now like that that’s all going to push back up there yeah because what’s in the top there and I’ll show you in a minute is an o-ring I don’t want that a ring damaged I think about this jars because that hasn’t gone according to plan and we don’t want to do it again so I’m gonna give this a wiggle on the top okay so what’s happening is yeah this is complicated so what’s happening is is that the o-ring is sat there this is also threaded here with the barrel if I pull it apart and you will see kind of what’s gone on so let me show you so there’s that bit first I will explain that bit in a second Benny’s being very patient he’s no idea what’s going on but I’m gonna continue and doing the cylinder so we’re free and it’s on an o-ring there and that’s separated off so let me explain without that hollow cylinder what’s been going on so what happens is this goes through the air cylinder this sits behind the brass ring at the front and this pushes through like that and then you end up tightening this against the front part here like that you can see it’s threaded on the barrel so obviously what happens is is when you undo this end you also stand the chance that that’s going to start undoing as well which is what happened so what we’ve got is we’ve got that apart like that so let’s just go ahead and take this bit off here now the only way that this bit is hold on here is there’s an o-ring right in there it’s an o-ring seal so the only thing holding that barrel in place into that moderator fitting and holding back all that pressure is a tiny o ring and and I think that probably doesn’t help I would like to see that maybe threaded with an o-ring or something like that because what you’ve got to do is rotate it and just give it a pull there we go and it comes apart and literally everything sits on this o-ring just in here the crowning of the barrel is lovely but the last men of the barrel is where their own ring sits and it’s hold that is basically a critical point the barrel as I say and I’ll explain this bit in a minute what I’ve done that threads into this part here you still with me out there you might be on your second cup of tea by now what I’m going to do is this bit needs to come off here sometimes it will undo by hand and sometimes it waits now you could put one part in a vise or you could get a friend to help you or whatever once you get it moved the mill it’s off you could apply a little bit of heat although I don’t know how good that’s going to be for it but I found that actually if I just get there you go and it’s got it so that’s it and we’re now undoing now it’s always about the o-rings always about the o-rings on on a rings basically make our guns work the pre-charge Agins modern air guns if a rings didn’t exist you wouldn’t have them so and that that’s the same as with any gun any high-performance gun any budget gun if it’s all based on a rings you NIC and o-ring mark mark and a ring you get a bad one in manufacturer that can cause you problems but anyway so we’re there this sides got one this sides got to so we’re going to just give it a wiggle there we go unless you connect her out and that basically mean that helps the barrel sit in and retain the air and so that’s your connection going through into that part there now when I got this this and there’s still a little bit of moisture there was absolutely caked in grace it was all caked in grease that was caked in grease on both ends that was caked in grease the barrel was caked in grease and that’s really not going to help you because this is your air reservoir so when you fire is going to come through there and it’s going to go through that valve which I’ve shown you earlier so this needs to be clean and the o-rings need a little bit of grease on them because they’re not gonna you know sit properly unless you do that but all this in here full of grease all that no you just don’t need it that’s that’s just the cheap way of putting the gun together so keep it clean and it will actually help accuracy and consistency a lot next we need to get the brass crown out and this is a vital bit as I’ve found so all I’m going to do is undo this Allen screw on the top and I’m using a two and a half and just undo that and then this bits going to fall forward it needs a little bit of encouragement a bit of encouragement like that just give it a little bit of a tap there we go don’t push on the middle of it just push on the outer edge this bit is so important in the accuracy of the gun what I found when I got mine originally this was in a really poor conditioning condition the crown was all bird everything inside was all bird and where it meets the barrel on the other side was all bird and scratched up so what I did was I took the o-rings off I got my dremel very very very finely this is you can ruin your gun if you don’t do this properly very finely took all the birds away and the reason for that is when this pushes back together this barrel sits inside there like that and the thing is that when you then push a pallet down you’ve got that gap between the barrel and the brass and if that gap is rough and serrated it’s going to skagle the pallet the pallets not going to fly true and what I had to do is this was like a razor-sharp edge here so again I took my dremel and I just ever so carefully polished it off so it’s more of a rounder smoother finish and then I changed the o-ring in there and the o-ring on there and I polished it all up but basically I got rid of all the bearing and all the issues and it fits together now really really well are you still there I’ve got a nice cup of tea that Ben’s made now I’m going to explain to you basically how a pcp air rifle works and the thing to remember is is that the layout that you see on this rifle changes depending on what gun you’re using in your manufacturer so more modern air guns things can be placed at different angles and whatever but this is the general basis of how it works here we go so what happens is to start the process off you would pull the bolt back that would then pull back the hammer spring against the trigger system the trigger system will engage and retain that bolt back sat on this area here when you pull that trigger that hammer flies forward under the tension of this spring at the back and it strikes the top of this valve just here which pushes forward and lets out a squirt of air this way and that squirt of air is regulated by this chamber in the gun here and it’s regulated by the pressure on these rings once that squirt of air comes out of that valve it comes up into the underside of the barrel and the palate goes forward and it’s as simple as that and these are my tips for how you can improve the performance usability and upgrade and downgrade the power on a standard pcp rifle first of all the bolt it’s the main bit that we interact with so needs to be as clean as possible always keep it clean you can put a tiny little bit of silicon grease on there if you want just to help it run but the bolt needs to be as clean as possible you can polish them there whatever you want with them and the probes as well need to be super super clean and I would keep that chamber completely free of tractor grease and stuff like that if this is running smoothly then this is going to run smoothly as well we’re going to talk about the hammer spring which is just here now these are the ones that people tend to know about first of all with adjustments now the harder this hammer flies forward and strikes that valve the more air that valve is going to let out so this hammer spring is kind of important it needs to run free and clear and this hammer needs to be nice and clean so you can make differences by adjusting that hammer spring sometimes you can use it on a thread system here sometimes you could if you wanted to actually change the spring itself and some people do and that can make a difference however to go up or down this hammer spring adjustment here is going to help you but clean and running as smooth as silk is going to give you the best consistency on the strike of that valve this valve here again is a critical importance for consistency of the rifle when that hammer strikes that pin and that pin moves forward I’m gonna try and do it like that and the spring pushes it back you want that to happen as consistently every single time now you can adjust how efficient and how much air is let in and out by that valve by changing the spring and the top of the spring valve itself so you’ve got this white bit just here these can be different sizes which means this spring is working at a different rate obviously if you get a different rate going on here you’re going to get and I’m gonna rotate this round for you because it’s roll around the other way you’re going to get a different squirt of air coming out through that port they’re going up towards the palate now some people would say that you could take a drill to that brass piece that is entirely up to you please remember that whenever you take a drill or make any physical changes inside this gun you’re gonna find it very difficult to put it back to how it was before so drilling holes really is an absolute last resort in fact I wouldn’t ever do it another place to look at is where your air sits so on here for example the air cylinder and I’m actually going to just move that down there just to help everyone to understand a little bit more the air cylinder is there so this is full of air and the air pushes through and it comes past the pressure gauge here and it sort of gets pre stored in this area and that priest store is controlled by that regulator now it is true that if you expand that storage by undoing the regulator you’ve got more air to come out through the valve system however that doesn’t always need to be the way it can be that again if you improve the efficiency of the gun you don’t need to adjust that regulator quite so much but the regulator is important keep it clean keep it in good condition don’t over tighten it and certainly never ever ever with the gun having air in it turn it clockwise because you’re simply pushing against 200 bar and you will Bend that rag and once you’ve bent the rag you’ve had it so anti-clockwise yes for turning the turning the power up a little bit never clockwise without inside the gun I’m gonna compare what I’ve just shown you to an FX impact and this is the smooth twist X 700 mill barrel so there’s a lot of external changes you can make on this rifle without doing what we’ve had to do with our rifle which we’re working on so for example the more refinements because the rifle obviously is more expensive this down here basically got a rubber ball in there and that allows you to adjust the bounce on that valve so when the trigger let’s the hammer go forward when the valve flies forward what you can do is you can adjust the bounce on that valve and that really is quite incredible you don’t normally see that on an air rifle but you’ve also got as I’ve said before you’ve got the ability to adjust the hammer spring on the outside and you can set it there under different levels to wherever you want you can also manually adjust using an allen key here which enables you to sort of fine-tune this area so working with this area and again with the valve at the front can really radically change the performance of the rifle the other thing to remember as well with with the FX’s is that it’s all drilled in very different ways compared to what you’ve got over there so for example the regulator on the impact as you know is in there if you can see and it sits at an angle going in and that’s what makes things so different between this gun and the Artemis m30 this has got external adjustability you don’t need to go to that level you can basically do everything but you do everything in the knowledge of what I’m showing you over there you understand what the valve bounce is you understand how the regulator plays a part but it’s you know it all plays its own parts you understand how important the hammer spring is and working with that trigger and then of course you know you also got the build quality the build quality on the FX is you know way higher than you’ve got with the art the Artemis m30 obviously there’s a price difference but they’re also both all held together with o-rings and that’s really really important this has got a rings in it so as that and the o-rings they do go wrong absolutely they do go wrong but it’s not something to get scared of it’s just something that happens you have an o-ring that goes a little bit there that’s life we’re going to put the gun back together and the first thing I’m going to do is put the brass barrel crown back in [Music] [Music] [Music] [Music] [Music] [Music] [Music] we’re ready to put a bit more air in and see if the guns got any more accurate okay so as part of the shooting process you’ve obviously got to get the rifle set to the right power for wherever it is you live so I want to get this just under the 12 foot param level I’ve got some weight pallets here which I’m the only out of twelve point three for 591 feet per second it’s a little hot for the UK let’s just fire one more just to be sure yeah so definitely too hot okay so what I’m going to do is I’m going to give that one whole turn out like that twelve point three one so it was still a little high another turn all the way out there we go okay so we’re now on eleven point eight which is just inside the sub twelve foot pound law obviously for the UK just going to do one more as well to see where we are yeah that’s nice so it’s eleven point eight two so it’s nice to consistent shots now something to remember is that I’m adjusting the hammer spring there for a big change in power the gauges on the bottom of the gun if I lift up here there’s nothing in it but the gauges on the bottom of the gun the regulator and whatever they’re pretty inaccurate I’m gonna be honest I would go to 50 and then maybe 75 and a hundred but it’s a pretty inaccurate gauge so you’re going to have to use a chronograph to get yourself set but you want the hammer spring to be working against the vial spring to give you the most consistent shot string and that’s what all that tuning process is going to be now I have made changes to the single shot tray I fold it down a bit and now it loads pellets as smooth as silk as you can see that works a lot better now ego that’s five from the magazine one to the side yeah I know but five from that magazine tune the gun it makes a big difference they are then that’s my tuning guide for the Artemis m30 straight out of the box I would say that for my 500 pounds I was thoroughly disappointed however I have spent a week plus tuning it cleaning it taking it apart putting it back together and I’ve learnt so much so in the end I really really pleased with what I’ve got but not straight out of the box however there are those of you out there that say oh what do you want to do all that for why do you want to pull that apart and make this and polish that and do that okay if you don’t you go for a top-end rifle where you can do everything externally like the FX impact but if you want to learn something you want to take your time and you want to thoroughly enjoy the internals of an air rifle then I can recommend doing something like that and you can go from a really bad group with your magazine it’s a five through the same hole and the o-rings they do go wrong so you have an o-ring that goes a little bit [Applause] [Music] I adore ingredients, because they are astonishing.

I love add-ons, because they are the helpful. HOW AN AIRGUN WORKS – How to repair and airgun – Beginners guide to the internal parts of a modern PCP airgun. How to remove and repair parts of a rifle using an Artemis M30 Chinese made rifle as a demonstrator. I bought this rifle for £500, was disappointed by the performance, so chose rather than send it back to learn from it. Tune and improve the performance. So I made a video with the help of Ben to show the basic principles behind a modern PCP airgun and how they work. Don’t let the repair process scare you.
