Great video ! Thanks for your work Tyrone . 👍👍
You're welcome K Lee
Great explanation!!
Thanks. I am looking to buy one of these as I have the CP1. There seems to be a stock problem with them in S.A at the moment but one supplier is hoping to get stock next week.
@Alex Bond-Smith I had a look at your channel and it looks really cool. Like the holiday places. Where do you stay in SA? I think there are some available online at pelletgunshop.co.za and on takealot, I also remember seeing some at out there 24 in Modimolle/Nylstroom
@@African-Budget-Pellet-Gunner Thanks. I have been in contact with the Pellet Gun Shop and they are hoping to get stock next week. Takealot have no stock. Can you tell me where you bought your scope from? I watched your other video where you talked about it. I see Takealot have 2 from different suppliers. One for R572 and one for R550. However on the cheaper one, they do not mention the rail size but on the more expensive one they do say 11mm.
@@African-Budget-Pellet-Gunner Forget to mention. I am in Cape Town. Whereabouts are you?
@Alex Bond-Smith yes Paul @ Pellet gun shot is a nice guy. I bought my scope from a local gun shop(Wildman) it will probably be 1 of those on takealot. It comes in a black box and only has the words in beige RIFLESCOPE 3-9x40EG. The name on the scope is Beileshi and it came with 2 scope rings as well. Just check that else you will need to get scope rings separate
Nice, I’m definitely gonna do this
Perhaps just look for washers to work as baffels
@@African-Budget-Pellet-Gunner yes i I’m going to the hardware store tomorrow I think.
Let me know how it goes
@@African-Budget-Pellet-Gunner i will, im actually going to town now. You wouldn’t happen to know the inner diameter of the silencer?
I believe it is 20mm and your holes should be at least 1mm bigger than the caliber
Thank you. I feel a 3D print design coming on. Which I will share.
Thanks Keith that is great if you are willing to share it, many will be very appreciative. I would even be willing to publish it on my channel. I do have another design which was shared with me that I can share. Drop me a mail tyrone8511@gmail.com and I will share that design with you
@@African-Budget-Pellet-Gunner Thanks, will contact you. Just need to find a CP2. The links you posted in another response, they have no stock. ??
Maybe try out defcon.co.za or security and more or huntalot they all seem to have stock
Great video!
Here in Sweden, the silencer comes without any baffles. Has to do with restrictions and license
@Chris wow ok so you have the casing but no baffles, the baffles can be replaced even by a washer with the hair curlers and felt and it will be effective
@@African-Budget-Pellet-Gunner Yes, it came just with the casing. I printed some baffles with my 3D resin-printer and this works really good! it´s sooo silent :) I used some little bit thicker "filter felt" for dampening. Question: Have you converted a PP800 PCP to the CP2? I also must say that I really like all of your videos.
I have not done the CP2 to PCP conversion due to having a pcp already and I do enjoy the co2 practicality and ease of use. Fortunately here in South Africa temperature isn't too much of a problem. Really glad you're enjoying the videos a whole series coming out now on the CP2 and mods
@@African-Budget-Pellet-Gunner Great! keep it up 👍
here its legal ,but i removed the baffles ,its not a loud gun as it would be without the silencer ,and those silencer wil with fillings and baffles get water and wil get more weight and that changes harmonics. with co2 not water but c02 ice (dry ice )can
Hi Tyrone, how do you stop the bolt movement flip when shooting the Cp1 pistol ? Couldn't find how on your videos
Depends if you have a newer or older version of CP1. Check out my reassembly video of the CP2, you will see there is a small grub screw underneath the bolt action which is used to adjust the movement of the bolt. If this is too loose it will allow the bolt to jump
Hi Tyrone. Do you confirm that the CP2 barrel thread where you put the silencer is NOT a 1/2 UNF and you need a special adapter if you wanna use a standard 1/2 UNF thread silencer?
Hi Mark, that is correct, the thread on the CP2 barrel is m10x1mm
@@African-Budget-Pellet-Gunner Thanks a lot. Greetings from Spain
I will share my findings while experimenting with silencer:
the vent holes only work effectively when placed in the back of a shrouded barrel with a good air stripper,
the shape of the baffles does make a difference and the more funnel shaped ones turned out to be more effective in my investigations,
the 4 baffle rule really depends on how the baffles are made and the power of your gun ... the more power the more baffles you can stack before you get diminishing returns,
the final air stripper at the end of the silence also plays an important role ... incidentally maybe that's why the funnel shaped baffles work better as each baffle is also actin as air stripper.
I have not had much success with PLA 3D printed baffles as they tend to shatter just with the shock wave of the higher power air rifles but might work fine with the kind of power the CP2 makes.
Personally I think that the CP2, even with the tuning mods suggested by Tyrone, is still very backyard friendly with the stock silencer. I measured in pistol mode 104 dB unsuppressed and 89 dB suppressed: the stock silencer suppresses the noise by 15 dB and that is quite impressive for such a small thing.
If you are looking for mouse fart quiet my advice is to get a phonometer and compare your results at each step making sure it is quieter rather then convincing yourself it is so. Keep in mind that human hearing loudness in not linear but logarithmic .... IE for you to hear something twice as loud the noise needs to be 10 times more powerful (about each 3 dB increase in noise level doubles the noise power) meaning that achieving 3dB better suppression already means that you doubled the gas flow capturing capabilities of your silencer and making your silencer half as quiet means that you are capturing the gases 10 times better.
I didn't even try my suppressor I got it an did two easy mods that made it where I can shoot in one room an no one in the next room of my trailer heard a thing I put a disk of acoustic soundboard in the tip of the suppressor in the screw on cap with the main hole for the pellet an a few small holes around the main hole an in the big baffle just a hole for the pellet to go through that disk now the only sound there is , is the hammer spring hitting but I plan on doing the spring mods so there not as hard the hammer spring an the one that releases the air but over all this is a fun quite air gun .
@ernest w your silencer mod sounds like a great idea to try, have you got more details on the acoustic sound board. Yes, I agree 100% the rifle or pistol is just plain awesome
@@African-Budget-Pellet-Gunner I got it off Amazon the brand is ( bubos) it's acoustic , soundproof absorbing panels . 12x12x0.4
@ernest w awesome thanks I think I might give that a try
@@African-Budget-Pellet-Gunner An my baffle order from left to right is the screw cap of the suppressor then two of the little baffles the big one in the middle then three little baffles then the part of the suppressor that goes on the end of barrel .
It was really tough breaking loose the red lock tite from the barrell. A heat gun applied to the barell seemsed to work best. How do you separate the sections of the moderator? They seem to be really tight.
Bonjour
Vidéo très claire et précise ….Mais où acheter le bigoudi ?
You should be able to get the curlers at any shop that sells ladies products. I got mine from the grocerie store
Tyrone great video thank you very much!
Is there a lost of accuracy or a lost of power when using a silencer ?
What is the most accurat pellet for the Artemis in your expirience?
Best wishes mick
@Michael Fuchs no definitely no loss in accuracy or power with the silencer. In my testing so far I would say the best all round pellet is the BSA blue star. The gamo magnum also does quite nicely up to about 20m. I am currently also testing the JSB Hades and they are fairly accurate as well, similar to the BSA but about 3x the price so personally I would just stick with the BSA blue star. Happy shooting
Great video. Do you have to drill the holes for this to work
@pronster1 no it isn't a must, the mod will work without the holes
@@African-Budget-Pellet-Gunner thanks. what length did you cut your hair curlers at
@pronster1 when you take the outside off the curler you will see there is some portions which have a little more support eg. Middle of the curler. I tried to stick to that
@@African-Budget-Pellet-Gunner thanks for that its very helpull . Could you just use the curlers and not bother to put the baffles back in
@pronster1 you're welcome, let me know how it goes
I have one layer of felt on the inside of the rings. and then put everything back. supper quiet, and supper cheap
Awesome glad it worked thanks for sharing your experience
The 2 holes ? Did you shoot before the holes? And then After? Was there a difference?
@Andreas Nitsch I didn't test it before and after the hole only before and after the mod
I modded the spring...... I still can't shoot the gun in summer I've got valve lock any ideas how to fix it?
I think I did a vid on this, will link it below but basically I would say the easiest is to put a 5mm spacer in the hammer in front of the hammer spring

Howdy Tyrone, man I dig your videos. I'm an ex south african living in Germany. I really need your advice. I'm a pellet gun tinckerer and I have just today recieved my Artemis cp2 in .22 or 5.5 mm caliber.
I immediately inserted 2 rubber washers 4mm and stretched the hammer spring on my second teardown to 75mm with the 8 mm rubber washer setup. I ported the gas🎉 valve, the brass magody and barrels to 4 mm. Did the trigger etc etc...all the mods you did, I did exactly. However, the silencer does not open up on either end. I have used a blowtorch to heat up the threaded areas in case there was tons of locktite but to absolutely no avail will any end open. So I drilled 1mm holes near the end as you did exept I drilled 6 because, when using the silencer from the get go, the gun reached 430 fps.???..I removed it to check for rimming but there is none and without the silencer on, I'm getting 549 average fps at 10,5 od joules.
Man...I'm really disappointed. There are no leaks near the pellet breach, I changed out the rubber O rings on everything and still, nothing like the 800 fps you got on your 5.5 mm CP2.
Can you please advise me as to what the issue could be???
I warmed the 12g umarex gas bottles up to more than room temp. Still, really kak fps.
please Help me Brother...🙏🏻
Hi, no problem bud, I will try assist. First Things first, just for realistic expectations, in .22 it is highly unlikely that you will get much more than 560-570fps. Unfortunately the co2 pressure is just too low. So from your comment it sounds like you are fairly close to that without the silencer.
So to strip down the silencer, the steps you have taken is what I would generally recommend but sometimes with that aluminum and loctite it really gets properly stuck. It should unscrew on both ends so perhaps try the other side.
If the silencer is affecting fps, it must be clipping somewhere, I believe the holes are usually 6mm so perhaps going in small increments open the the silencer hole which goes through the ends and baffles(the main hole where) pellet goes through to 6.5mm, 7mm, 7.5mm until it stops affecting fps.
The other this is try changing your gas to perhaps ASG that seems to work best
@@African-Budget-Pellet-Gunner wow, Bro I appreciate your quick response and valuable feedback. From the sounds of the Hardy Dah birds in the background on ypur videos, I'm guessing you living in P.E. or, somewhere in the lovely Eastern Cape. Yes, I will definitely try opening the silencer. I did try both sides but to no avail.....things I'm a bit OCD and scratching or chaffing the aluminium really freaks me out. Anyway, I suppose I'll just sand and polish the aluminium afterwards.
Thanks again bro.🤜🏻🤛🏻
Haha, I used to be in Ellisras, but I am in Centurion now. Let me know how it goes with your CP2
@@African-Budget-Pellet-Gunner Hey Tyrone, man I just can't stand this tech. I sent a loooong reply back to you 3 days ago, which obviously did not go through.
In it i was explaining how I almost destroyed the silencer, having to heat it up with a blowtorch and finding so much locktite on all the threaded ends that, I am totally convinced, whoever assembled this at the factory has a penchant for locktite and a hatred for tinkerers.
I couldn't reinsert the baffles or baffle plates as they just would not go in without becoming stuck again and deforming...even after careful sanding.
So I had an idea, which works flippin well actually, I took a small paint roller, (long haired), removed it from the handle, removed the end caps and found the plastic tube the roller hairs are stuck to, to have an inner diameter to be around 7,5 mm...perfect.
I heated the tip of a thin screwdriver to push through both sides of the roller, roughly 6 holes, of around 3 mm thick, inserted it, (by the way it self-centres), and....BOOOM!...silent shooting...very, very quiet actually.
So, onto another question bud.... I performed all the power output thingies you suggest except, I never really removed any thread from the valve yet, and I'm getting roughly 579 fps in rifle form and about 20 shots before a noticible drop in power, as the gas is depleting more rapidly, I know.
However, should I remove some thread or drill out the valve, for a bit more volume, even though I'll lose more on shot count...what kind of power increase in fps would this result in and, is it worth doing, if I want the fps and am not worried about fewer shots ???
Thanks Boet and I hope your doing alright hey? ✊🏼
@rausdashaus777 wow seems like that silencer really gave you a tough time. I wouldn't mind seeing some pictures of your new silencer.
I wouldn't recommend cutting the threads off if you are already around the 580fps range, I think you are at the point of diminishing returns. You are welcome to drop an email tyrone8511@gmail.com if your comments are getting removed
Would it be any benefit to drill the holes without doing the rest?
I think it would be very slight, the holes are to try allow the extra gas to escape, you however need to absorb/catch the gas first
Scotchbrite might work even better instead of the felt as is a very much looser weave. Maybe just then use a smaller diameter hair curler to accommodate the thicker Scotchbrite wrap, otherwise you May struggler to make it fit!! 🕳
Scotchbrite may very well work better for sure, I will need to try it
I can't unscrew my silencer. Maybe it's glued together? Left or right-hand thread?
It is standard RH thread, it is a little tight sometimes. Just wrap a cloth or elastic band around and then use a water pump pliers to loosen it up
@@African-Budget-Pellet-Gunner Thanks!
I have the Artemis Cp2 but I can't seem to open the silencer. I've tried pliers there is no movement at all. Any tips on how to open the silencer?
I managed to open one side. Can confirm they used some kind of glue on the threads. Completely screwed my silencer with the pliers. Have to sand and repaint it...
Hi, yip in certain countries the laws on silencers differ, so sometimes they glue it to keep them from being opened. Sorry about that.
Does anyone know where I can buy that silencer from I’ve lost mine
I can try point you in the right direction, where do you live?
Barrel is too long will a shorter crosman barrel fit
No but the CP1 barrel will fit
so, Tyrone..does the baffle "absorbtion" act to decerate the pellet...? so, silencers slow the pellet down...??
Thanks - love your stuff.
@Kimberley Ainsworth the baffles shouldn't slow the pellet down, we just need the baffles to catch the excess air so that it doesn't escape out the front. The more air we can trap the more effective the silencer. It should not slow the pellet down
@@African-Budget-Pellet-Gunner Thank yoo! I am going to check my Physics on that one. But you shared a great little mod. :0 )
@Kimberley Ainsworth you're welcome, glad you enjoyed the video and Thanks for reaching out

I was hoping to hear you say "bigoudis" but I guess curlers are fine.
Any silencing device is prohibed in kenada 😥
Sorry Lowkey, you have a lot of laws to deal with
@@African-Budget-Pellet-Gunner atleast our curlers are sounding nicer!
Bigoudis 😎
You'll be surprised how many words are completely different for the same thing. If I talk about a bakkie you will probably think I am crazy
@@African-Budget-Pellet-Gunner according to internet it is a "useless truck" as I call them haha
I believe bigoudis is the french word I just never had a chat with hair stylist so I didnt know the english word..it does make alot of sense tho haha
I wouldn't say useless truck, all trucks/pickups in South Africa are called bakkies.
No worries I think I visit the hair salon less than most people 👨🦲
before you fit a muffler check the crowning on the end of the barrel as bad crowning will play hell on a muffler!
Agreed 100% but I must say the crowns on these barrels aren't bad
Did you happen to measure the FPS before & after ?
Mods on the silencer won't make much if any difference to fps unless it is not aligned and is clipping but then the accuracy will also be terrible
@@African-Budget-Pellet-Gunner Although I haven't checked it myself the guy at AAR on Air found that the standard silencer actually increased the muzzle energy of CP2 both in pistol and rifle configuration. I guess this is because there is still some propulsive pressure behind the pellet as it passes through the silencer (or the early part of it at least).
I suspect it will be very similar almost negligible. But I do trust Andy at AAR he is usually very reliable
@@African-Budget-Pellet-Gunner Thanks for the reply. Yes, Andy is a handy source of information. Unfortunately his channel is so big now I can't find the right video at the moment. I think the change was small but he was quite surprised that the gun hadn't actually lost power such was the reduction in the bark compared to the un-silenced state. As I'm using the gun for ratting I'm happy to live with whatever power I have with the silencer fitted as, at close range, it's more than enough.
Agreed 100%, this silencer is definitely sufficient, you know us as humans like to always tinker. This is a perfect tifle for ratting for sure
Great video, your mods are a good mix of a baffle and a Weihrauch sytem silencer i think. It‘s sad that any kind of silencers are strictly forbidden in my country, had to buy a pretty expensive airrifle to dont disturbe people to much 😢😉 cause most 40 joule guns are barking like hell
@Andreas Budischek Thanks for your kind words glad you enjoyed the video. I can only imagine that a 40J air rifle will have a serious bark even this CP2 has a bark without a silencer. So what is illegal buying and modifying silencers? But you can buy a rifle which already has a silencer
@@African-Budget-Pellet-Gunner in Austria you‘re not allowed to own a silencer without a hunting permission and those are real expensive plus you have to make a license first that also cost a lot and is not easy to make
@Andreas Budischek that is pretty tough, guess it is an advantage for me living in the South Africa. With regards to air rifles there isn't too many restrictions. I think there's only a restriction on caliber but nothing on power output.
@@African-Budget-Pellet-Gunner the power is not restrictet and calibers under 6mm are free to buy if you older than 18. for bigger calibers the dealer have to send your all the paperwork to the district government and from then the gun is in the countrywide system till it dies😜.
With that you also give police the right to come to your home and check that you have it locked up seperatet from ammunition like you have a firearm.
Our weapon laws only get topped by the Germans i think, they‘re only allowed to have 7,5 J or have to make a license for firearms. But they are allowed to have silencers on those week airguns 😂😂
By the way: tomorrow i‘ll try (and maybe buy) a FX with massive power.
Where can you order an extra silencer
Where do you live Russ
@@African-Budget-Pellet-Gunner Colorado usa
Hi Russ I am not 100% sure for US but I know previous the guys commented www.trrobb.co.uk or Google John Knibbs
Russ. If you dont find what you're looking for check out "Buck Rail silencers". Terry harman does 3d printed silencers for cheap, and they all work great. I have about 6 of them on my 1322's and 2240's and QB78's. Google buck rail silencers...good luck!!
@@gwhitfield4239 thank I noticed a couple of days ago they just started selling them again, he stopped selling them for a while because of confusion over new gun laws.
Thank you for the video. I’m under the impression that you can’t remove the silencer from the stock Chaser rifle barrel. You obviously did. How did you remove it please.
It just screws off. Sometimes it has a bit of lock tite on the threads, you can just give it some heat from a hair dryer and it should screw off easier
@@African-Budget-Pellet-Gunnerthank you very much
@kelalamusic9258 you're welcome, let me know if it doesn't work
@@African-Budget-Pellet-Gunnerit’s because of this issue I’ve held off purchasing the Chaser kit that comes with the rifle barrel. I just checked with a dealer and he mentioned that they come from the manufacturer permanently attached to the barrel. Now I’m really confused. 🥴
I have had 6or7 CP2/chasers that I have personally worked on and all of their silencers were able to be removed. Unless there is some laws where you live specifically around the silencer. Even if there was a law it would just be done with some locktite
Something I learnt today, on www.airgunforum.co.uk/community/index.php?threads/absolutely-gobsmacked.224030/ is that a CO2 will maintain 850psi (60 Bar) until the liquid has gone and you only have gas left which will be soon gone. Which means CO2 effectively has a regulator.
Nice, but what has this to do with moderators?
Well there you are, you have a nearly constant 850psi. Initially the pressure will be a bit too high and the valve will shut early so you have to shoot a few pellets until the airgun comes on-song but then it should be consistent until the liquid CO2 has gone. And for this reason it is perhaps worth waiting a few seconds between pellets for the CO2 gas to evolve from the liquid as it is not instantaneous.
At one time my work entailed measuring pressure waves from military explosives ...
When a CO2 airgun is shot (I don't think an airgun can be fired), the expanding CO2 drives the pellet up the barrel which drives the air in the barrel ahead of it forming a longitudinal sound pressure wave. That pressure wave goes into the moderator cones where it is compressed and reflected. That rebound should occur as the pellet is transiting the moderator thus assisting it on its journey. With the pellet away from the barrel, the excess spent CO2 is now trapped in the moderator thus dissipating and silencing its retort.
This is not entirely different to a motorcycle exhaust system. If you simply want quieter you put sound absorbent material in the silencer. As you have done. If you want greater efficiency you arrange for pressure waves to be reflected to create a partial vacuum which scavenges the exhaust gasses out, and it's still quieter than taking the silencer off. And which gives our airgun pellet a few more legs.
@Jeff Slade Thanks for your comment, you really have a wealth of knowledge that you bring to the table. Thanks for sharing.
co2 is depending om temp at 5 celcius only 10 bar at 30 celcius 65 bar, thats why the co2 gun is not for cold climates . for 10 m olympic they start with co2 after the recoilles springers ,but soon it was the pcp ,because the pressure is more controled. but also somewhat dependable on temp , i shot a pcp gun that got frozen at the outside , the expanding gas works like a freezer system . springers also like warm ,,you get less heat and airvolume in the cold ,and less speed
I agree with you, I am fortunate where I live we never get to very cold temps
Pourquoi vouloir bricoler ce petit modérateur de son ??? il fonctionne très bien comme ça !!! Quelle perte de temps !
You did the stupiest thing you can do with a silencer. A silencer does not only suppress noise, it is also an air striper for accurate shooting. You destroyed the silencer. Have you ever shot your gun with and without supressor???
Yes, I have shot it plenty with and without the silencer, it doesn't affect the accuracy. Welcome to the channel I guess
