- 3 easy and reversable ways to increase your #Artemis #CP2 #fps Tutorial
This video also discusses how to take the Artemis CP2 apart and how to reassemble the complete air rifle. We will also discuss how a co2 airrifle functions so that we can understand how the modification works and which modifications we can make.
3 options
- spacer inside hammer
- stretch hammer spring
- install a smaller valve spring
We will then test to see what is our fps increase using Chrono Connect App link to app testing below

Hey! I finally made one detail. Now it can be PCP too. Speed 205mps for 0.57g bullet, short barrel. 10-12 shots. It is fashionable to buy a pump for $ 40. If interesting....
Are from an alternate " Reverse " universe? That would explain why all your screws
are reverse threaded.

Excellent series! I Followed these vids and now I can shoot through 2 x 2mm thick stainless steel plates at 25m with my CP2. My beloved little lazer beam now kicks ass
Hello. And to increase the weight of the hammer by installing a metal gasket in the form of a mushroom.
It will help but not as much as drilling or increased hammer spring tension
Hi again Tyrone... I bought a more powerful spring from a guy who engineers them specifically for the CP2 to save stretching.....
If I did the 3rd mod on this video as well (less powerful spring)... Would this add yet more power? Or is it just one or the other
You can combine the mods but the results will be determined by how well balanced the mods are. You might do 1 mod and then find less than desired results and then do the next mod and get more than expected. As the balance is better so better performance
Your mirror image filming is confusing?
Sorry about that, yes some of my older videos were unfortunately with the selfie camera. The new videos are much better
Where can I buy a lighter spring for the co2 valve?
A lighter spring for the co2 valve won't help you at all, waste of time
Haha understood. I only asked because, well.. you mentioned it in your video lol
I can already see, I didn't pay attention. Gamo Magnum.🤣
Realy gud explane, what goin on inside the co2 gun.
Thank you much :)
@Vladi glad you like it, I think you will enjoy my next video as well. Thanks for your kind words
Good job but the front camera is misleading. It's the opposite as if in a mirror.
@ladislav kiss Thanks glad you enjoyed the video, yes you are correct, sorry it is a little misleading with the selfie camera creating a mirror
This was just awesome, bought a CP2 in. 22 and shot it a bit... No thrills but after I did all the mods it's a little monster... Thanks for all the vids and advice. Next gun is a PR900
@Naas Ferriera Thanks for your kind words and welcome to the channel. You will find loads on the PR900 as well
I have seen all the vids thanks... Just need the gun now then I'm ready to work on it... Would like to run the CP2 through a crony at some stage to see what it does, I didn't cut the thread off the valve casing to increase the volume, i used an 11mm drill and drilled towards the seal side and took about 5mm out then sanded the inside with a dremmel and some accessories, this worked perfectly and I shot 4 inches higher than before with all the mods... Even the trigger polish was a success.
Awesome I glad the mods worked out. The trigger definitely assists with accuracy and consistency. Please keep us posted on your progress and results
er mirror imige
Hi Brian, sorry about that, I was still learning at this stage, please watch this video instead th-cam.com/video/Kh1zydTogq0/w-d-xo.html
I Problem a few people here got with ther diana chaser is that the Handel brakes of . If the spring has more Tention then load with your Fingers near to the body of the loading pin.
@Andreas Nitsch I have not had this problem myself but you aren't the first person who has told me about this. What I can suggest is when loading up the action put your index finger as close to the action as possible and when pushing the action back in to load the pellet, maybe use your thumb to push on the shaft protruding at the back. Hope this helps, will try show what I mean in 1 of my upcoming videos.
I get 20 shots out my Diana chaser after Tunning..at a 720fps without long barreel
@AIR Airguns Included Reviews that is awesome with a longer barrel you will definitely increase your fps as well. Which of the mods did you do? And what pellets are using to test? Thanks for sharing your results.
I was bussy for a couple off months with this build !! Almost everything is modded
Transferport
Barrel
Breech
Valve
Bolt
Spring all modded
Its like a laserbuild now 🤘
Awesome, have you got some pictures, I would love to see it. tyrone8511@gmail.com
.177 or .22?
@Bevan Lourens my CP2 is .177
Try switching your spacer out for teflon or aluminum. Or you can trim a longer spring to length and omit the spacer. You can also make your own spring with music wire.
@American Defender Thanks for sharing your ideas, I think I definitely like the idea of making my own springs. Thanks for your comment.
Доброго времени! Ваши видео крутяк! Приобрёл по скидке такой предмет. Рассверлил перепуск, заменил пружину, утяжелил ударник, поставил длинный ствол. Теперь этот пистолет может! Хочется придумать к нему резервуар, который можно было бы дозаправлять из углекислого огнетушителя. Что бы не использовать мелкие баллоны со 2.Good time! Your videos are cool! Bought this item at a discount. I drilled out the bypass, replaced the spring, weighted the drummer, put a long barrel. Now this gun can! I would like to come up with
Thanks glad you enjoyed it, sounds like you've done a few mods
Oh isee its an orrofice valve i can also turn a new pin so it can push the orrofice valve open for longer its actually quite a simple weapon design
Yes you could also change the pin in the valve
Or ad a softer spring at the back of the orrofice
Yes i know . But it is not a must . It already gains more Power without drilling the barrel
. Massage is for jeff
Thanks for that dis-assembly lesson! Anxious to see the performance out of it.
Your getting me a bit more primed for my mod. Having a hard time getting my hammer cap out of the housing. It is binding up substantially.
I May tap a hole in it from the back, insert a screw and use that to pull it out.
Hi Bob, the Hammer cap should come out very easy, it only has the 1 cap screw holding it in place. Perhaps use a water pump pliers on the extruding piece and try turn it, it might have a little glue around the outside, please share how you mod goes
@@African-Budget-Pellet-Gunner Tyrone is it true that using the magazine reduces accuracy, best to use the single train?
.. I thought I heard Andy's airguns AAR mention this
I think it is a bit of a mixed bag. If you adjust your mags to work nicely they are really not bad. What I have found is use exclusively 1 or the other if you use mags, only use mags and you'll be fine as if there is any deformation on the pellets it would be consistent. However in the pursuit of ultimate accuracy you are probably better off using the single shot tray as Andy @AAR mentions.
@@African-Budget-Pellet-Gunner Ahhhh... such an intelligent answer thanks very much
Nine is doing 510 fps with 27.28 grain pellets (.22)
19.7 joules (close tô 16 fpe) with lighter pellets 18.2 grains
@Julio de Oliviera F that is awesome, so I assume that you are happy with the mod. Which modifications did you do? Just for interest sake, what is your shot count on a co2 capsule/cartridge
I'm uk based so 12ftlb is the limit for me . I found in .177 the barracuda match heavy from h@n gave good results also the pro hunter hand swaged slugs did well too but they are designed for sub 12ftlb rifles .
@Ray Morris Thanks for your comments. I actually haven't tried the h&n barracuda yet, to be honest haven't even really seen them in the shops, will need to shop around, maybe I can try those pellets next
9 shots without any change in fps 12 more with steady drops
I did the transfer port drill to 4 mm and plan on doing the valve spring with lower power
@@juliodeoliveiraf8470 you can buy custom transfer ports up to 4.5mm I left mine standard and adjusted everything else 10ftlb is more than enough for target shooting
У меня, была стоковая пружина 80*10*0,9 мм. Её убрал. Заказал 90*10*1,0, вывесил ударник, обрезав пружину, вкрутив в неё обрезанную ( как бы телескопическая), для устранения повторного удара по штоку клапана при отскоке ударника ( устранил резонанс колебательной системы), увеличил массу ударника на 4-5 г, и собрал. Хрона нет, но с 5 м, 20 мм доску навылет. Повторных ударов по штоку вроде не стало при отстреле баллона со2 до конца. 18 мощных выстрелов + 5 средних. Порты рассверлены на 4,2 мм, спуск отрегулирован, ударник и место его работы зашлифованы. Заказал хрон. Самому интересно замерить. Калибр 5,5, ствол длинный...
@igor Egorow looks like you have a pretty powerful rifle now, I am working on a method to eliminate hammer bounce hopefully will be able to release soon. Thanks for sharing Igor and please also share your results once your chrono arrives
@@African-Budget-Pellet-Gunner , конечно.
What ammunition did you use for the test at the end of the video?
The pellets I used was the gamo magnums 7.5gr
We only have to buy a export piece for 8 Euro. Its got a 3mm hole , the one build in has 0,8 mm . To build it in , 10 Minites. Not alowed in Germany but in Austria. Much more Power.
Do you mean the transfer port between valve body and breech/barrel? The brass part on the UK (6-ft.lb max pistol) fits the shank of a 9/64 drill. And which is loose on a 3mm drill. The trick is to align the valve and port with the drill shank before screwing the valve into position.
@@jeffslade1892 thats true . But you also gain more Power without drilling the barrel Port. You will get more Power if you do drill. But for me its ok with only the 3mm brass port
@@andreasnitsch8119 I think something got lost in translation. You contradicted what you said, "But you also gain more Power without drilling the barrel Port. You will get more Power if you do drill". Please explain again.
I observed on my CP2 that the barrel breech block aligns perfectly with the brass transfer port, but that the brass transfer port does not align perfectly with the gas release valve unless a suitable tool (the shank of a drill bit) is used whilst fastening it into position with the screw. A set of imperial drill bits in 64ths is useful because they sit in between the metric sizes.
The CP2 is already reasonably powerful by UK standards; I am getting pistol around 500fps from a medium pellet. Making it more powerful means the CO2 pressure drops more rapidly, which is detrimental to grouping. Some of the mods means only some 20 shots before the CO2 is gone; first and last shot will not be equal.
From new, the gun actually benefits from being stripped apart, serviced, and reassembled meticulously.
I love your channel. Which upgrade do you advise ? Spacer ? Valve ? Spring ? I see some 90mm spring on sale on ebay
@Jc dupuy, the first mod I would advice is adding spacers into the hammer. It is the easiest to reverse as well. A 90mm spring (od=10mm wire=1mm length=90mm) you can go for it, it will have the same effect as stretching the spring to 90mm
@@African-Budget-Pellet-Gunner thanks. Spacer + spring. What kind of fpe can i expect ?
@Jc dupuy with 8mm spacer and 90mm spring you are looking at 680-720 fps in .177 so about 8-9fpe. Which if your accuracy is good is more than sufficient for pest control or small game hunting
at 2:41 you remove the hammer spring. When I undid that screw, I found that I couldn't get that end cap off, so I couldn't get to the hammer spring. Is there a trick to getting it off?
@Patrick Renschler mine personally just comes out but some subscribers have said that theirs was held in place with some kind of adhesive. This may be the case on your rifle. What I can perhaps suggest is to try turn it on that bottom protrusion perhaps using a water pump pliers. I believe @jeff slade drilled a small hole in the end cap and got it loose with a small sliding hammer.
@@African-Budget-Pellet-Gunner thanks! I measured my ports were < 3mm! going to try 4mm or 4.5mm
Sounds like a plan just remember to drill it incrementally. Don't try to drill straight to 4mm
@@African-Budget-Pellet-Gunner thx you saved me, that was what I was going to do hah
Here in the UK you can buy kits to upgrade the cp2/chaser . I bought a upgraded hammer spring and spring stop this cost less than £20 . There are many other they sell wider transferports complete reworked valve systems with lighter springs. Adjustable hammers heavy hammer spring guides and top hats to add weight to the hammer strike . I imagine you could really up the power there are even Pcp adapters
@Ray Morris Thanks for sharing this with us and please will share the link to the shop with us. It is always fun to tinker a little with the guns.
@@African-Budget-Pellet-Gunner yea the guys name is Terry Robb and the website is .. T r Robb.co.uk .. just as a side note the cp2 (my one at least ) limes the pro hunter standard slugs .. these have a better ballistic coefficient than diabolo pellets but are a little pricey at £11 for 100 . But they do not hard and are accurate
@Ray Morris I will definitely need to try get hold of some of those slugs perhaps do a video testing them, I have currently gone a little old school testing some round lead ammo
Here in Germany 8 Euro. Then you got 3mm and the one inside had 0.8 mm . So easy
@@andreasnitsch8119 www.trrobb.com/ that's where I got my parts .. you can also Google .John knibbs . For original parts for airguns .. and if you go to pro hunter swaging on facebook you can see the group's I sent them from my 10ftlb co2 rifle at 25m
I saw a few photos of a pcp bottle modification for the CP2 , or it looked like a PCP bottle .. it was on a SA forum. Any ideas about this ?
Yes, it is very possible you will however need to order some of the parts from across the pond. There is basically 2 options.
1. Is called a safepac which can be bought from Froggie in america but this is unregulated and low shot count
2. Install avdrop block with a hpa/co2 bottle. This is the better option as the bottle is regulated and you will have a decent shot count. The drop blocks are manufactured by Sheldon Norris in the UK or Froggie in the US, there is many bottle with reg options the most common is Ninja bottles.
These mods are common in the uk because of the low temps and the effect on co2. A couple of things to consider, you will need a fill source ie pump, scuba tank or compressor this is a minimum of R2000, more likely R3000+. The conversion will cost you upwards of $120 if you include shipping. Add that to the price of the CP2 you could have bought a PR900.
I just bought one of these for my son and I to play around in the back garden with and I just want to say thanks for this video. I just put in two perfect spacers and wow it definitely worked. the fps is much better. total 8mm thick. thanks for your vid was easy to follow.
That is awesome! Glad I could help and welcome to the channel
Hi Tyrone do you know if there are spares available for this pellet? Mine leaks gas so is basically unusable.
@CartoyzTrading can you perhaps give an indication where your rifle is leaking then I can be able to try help
@@African-Budget-Pellet-Gunner I have not opened it as yet. But as soon as you pierce the CO2 cartridge it starts leaking. Takes maybe a minute or 2 to empty the cartridge. Gun was stored for a while. Worked perfectly beforehand
@CartoyzTrading ok well it is most likely leaking where your co2 cartridge is being pierced. What I would suggest is get some silicone based oil or a grease which is designed to work with rubber, eg. A cv joint grease. Just put a little bit of Either on the front of the co2 capsule. When loading the capsule turn it in a little by hand and then use that extra front pin/bolt to seat the co2 capsule. Let me know how it goes
@CartoyzTrading check out this video I just loaded, it should help, th-cam.com/users/shorts-q-WIDydb1o?feature=share
@@African-Budget-Pellet-Gunner you need to tighten the cap faster .. make it hand tight then use the tool to make the last turn quickly .. I found that the milbro c02 tanks are a little fussy and can vent gas if it's not tightened up quickly
Have you tried polishing the inside of the tube the hammer slides in?
As supplied mine was pretty rough. Polished up with fine wet n'dry on a wooden mandrel driven by an electric drill. The hammer is a loose fit so it doesn't need to be mirror finish perfect, just so it can slide without hindrance and reproduces consistent shots.
Without any other modifications, on the pistol barrel with silencer, first shot on a new CO2 went over 720fps and some ridiculous ft.lb. Subsequent shots dropped back to a respectable ~520fps and >5-ft.lb, and under UK legal limit.
Personally I would rather have consistent power for accuracy over ultimate fps. Even with this little boost I'm still getting 40+ shots before the accuracy drops off. Personally I'm using it as an iron sights target pistol, although I'm far from a good shot.
@Jeff Slade Thanks for your comment and I can see that you have been busy on your CP2, awesome. This suggestion will probably be 1 of my next videos but with a twist of course. Happy shooting
@@African-Budget-Pellet-Gunner yes, it is worth examining that sleeve especially over the weld which may have caused some distortion and corrosion. Mine was also covered in scratches and little burrs.
Slotted wooden dowel long enough to go right through, wet and dry wrap about 4-inches, big screw up the back with the head sawn off to fit electric drill. A bit like a flap sander.
Please note I am not disinterested in increasing power, however I am more interested in improving the gun to give better grouping.
Thank you for your videos.
I normaly write in German 😅 . I ment that the most Power you get is you drill the barrel Port also . But the Power already increase with the brase Port. Now i found one with 3.5mm.
@@jeffslade1892 the one that Was in original has 0.8 mm
@@andreasnitsch8119 0.8mm is ridiculously small. Are we talking about the same part, the brass transfer port, the piece with two O-rings? The brass ring that fits between valve and barrel? Part No.27 on the parts diagram? A tiny hole like that would be as much use as a chocolate teapot.
Buy a set of /good/ HSS imperial drills in 64ths. for example 9/64-inch is 3.57mm, many guns parts are sized in inches.
My german is non-existent, so you have the better of me. However I have noticed many times that german-english translation can turn the meaning backwards.
