- A comparison between a real gun silence construction and a PCP silencer.
The real silencer was kindly provided by Nielsen Gun Parts and the PCP silencer comes from AirForce Airguns.
They are both made for 0.22cal projectiles however both have very different designs, i will explain in simple terms why.
Note:
PCP silencers/moderators can not be used for firearms. The suitability of a Firearm moderators/silencers for PCP can not be guaranteed as the ballistics for fire arms are completely different for expanding air. The velocities of a PCP pellet or slug are too slow for a typical firearms moderator construction, where internal turbulence can adversely affect the exiting trajectory.

Nice
There a company called wolf for PCP but there made similar to the can for the 22 lr you showing there just not anodized black but very similar in build very interesting.👍👌✌️💯🎯🍻🇺🇸
I'll check them out, very interesting. Thanks for watching and commenting.
Are they legit?
Haw mani price of silencecer one piece
a muffler is a muffler, what makes a muffler effective, makes it effective no matter the gas outlet it's attached. A simple blast chamber is better than nothing, but it doesn't compare to having a means of disrupting the flow of gas (usually baffles, although Maxim, De Lisle, and others tested/used helical internals at one point or another). Yes, I said it, the point is to create turbulence; as once the gas hits the blast baffle, the bullet has outran the gas, and anything that happens from then on doesn't really effect the bullet in any appreciable way. What works for firearms, works for airguns, because they do the exact same thing (you can even look at car mufflers for ideas)
The big differences are that pre-compressed gasses that rapidly expand cause a drastic drop in temperature (to the point where the air can liquify in extreme cases) (and firearms compress the gas as it's produced, similar to how your reservoir heats up as you fill it, just orders of magnitude greater in firearms), and this can cause issues with cold embrittlement; and that air rifles can't generate the same amount of gas that most firearms can, allowing you to get away with lighter materials for air guns.
Silencertalk is a great resource. Make sure it never touches a firearm, That it was never meant to be a firearm suppressor, and that you would never consider using it on a firearm; and the feds got nothing, the courts have ruled repeatedly that mufflers for anything BUT a firearm (as defined in the NFA) are not regulated by the NFA, just like I can have a 15 inch barrel on an air-rifle and not pay the illegitimate tax, and I can have a 17 inch barrel air-shotgun without paying for a stamp.
Where people start running into legal problems is when they start making "mixed use" mufflers (which is a big no-no without an approved form 1) (usually these guys are also selling them as such (which attracts unwanted attention), also a big no-no without an FFL- class 7 and a class 2 SOT cert)
Totally agree with you here. Yes indeed on the many airgun channels and those using big bore airguns one can indeed see the condensation occurring at the point of gas expansion whether that be just the muzzle or the "muffled" end.
I did perform tests (not shown here of course) for a particular firearms company as to whether one of their products would be suitable for airguns. It was certainly not exhaustive at all however one rifle, it wasn't suitable. unfortunately I could not hire a high speed camera with sufficient frame rate in order to examine the projectile as it exited the barrel. This would have told me a lot of information. We did repeat these experiments many times and at no point could we get accurate impacts, let alone precise. Many thanks for your comments.
@@bctpcp9546 and yet, the leading company selling airgun mufflers predominantly uses a drilled-bar monocore design with baffles; and several of their competitors use "K" or "M"-baffles, go figure. Biggest issue with adding a can to the end of a gun barrel is that by adding weight to the end, you completely change the way the barrel oscillates during the shot. That means that what once may have been an accurate loading/tuning before probably isn't now.
@@wildrangeringreen Look too at some of the old Russian and others, who simply used several "washers" ok LOL orifice plates to lower the sound level. I seen them sired and they really do work, without the fancy pants milling prevalent today.
@@bctpcp9546 flat baffles work pretty well, especially if you have a fair amount of volume.
@@wildrangeringreen Yeah for sure.
I can't find that suppressor for the pcp anywhere .... And I have been looking and looking ... Help?
This is a very old design as in 10 years old and it may not be available any more. I bought it from "shop soiled stock". It was literally covered in dust sitting in a gun shop window for maybe over ten years. I just chanced upon it (I wasn't even in the shop for such an item LOL). You will probably have to look for similar from independent manufacturers or ask a favour from a friend with a lathe.
It is just a big volume and essentially one "orifice plate" design. So unlike many "new" designs where the last orifice is not a plate but forms some sort of conical profile, the orifice plate has been well documented for lowering noise levels and can be seen on many early designs for true firearms (rare to be seen for PCPs, I believe); and of course all the funky variations of the orifice plate for true firearms silencers/suppressors when you start to look closely.
🥰🥰
Iv definitely considered how much of an awkward conversation I would have with rhe atf if it did ever come up because as far as I can reason they can't classify it as a suppressor even though functionally a suppressor and a moderator are the same thing just aimed at different applications.
This is def a big topic for sure.

Interesting!
✊🏻✊🏻✊🏻 open up atf !
I swear I'm innocent!
@@bctpcp9546 no officer I clearly baught it as a solvent trap and only after receiving it I realize it could be repurposed as a moderator for my aea terminator. Yup just like the donny fl moderator I can legally purchase and ship to my house because it's marketed specifically for air guns.
The funniest part is that the atf is basically making laws at this point and even still they are having so much trouble legally defining stuff but it's still not illegal somehow.
Can we fix silincer on SDB 0.177 Magnum??
Only unless the end iron sight can come off, just for starters.
You know who makes these for a Diana 34 .22 Pellet rifle?
Is the end of the barrel threaded at all, I'm not familiar with that Diana?
Maybe you would have to remove the end iron sight (if even possible)
@@bctpcp9546 no just a removable plastic tip for iron-site.
@@WILLY52368 Mmmm, then it might be a bit tricky. If you can remove the barrel and get the end tapped male for appropriate device.

I'd love too! I am the dumb one in the family my wife and child speak several languages! Thank you for watching anyway!
Will i get in legal issues when I put on a Moderator on my Air rifle?
That depends upon what country you are in and the local laws. It is not a given rule that a moderator can be used legally upon any PCP air rifle. You must check your local laws. Thanks for watching.
