View Full Version : suppressor question

November 9, 2010, 09:27 AM
Just a question about pressure. If you have a suppressor for a pistol and want to use it on a rifle, will the difference in pressure from the rifle damage the supressor the long run? Thinknig about getting a suppressor for my Walther P22 and use it on a S&W AR15-22 or AR7.

No, it will not. .22 cans will be fine on either a hand gun or long gun host.

Before you do this make sure your intended host semi auto rifles will cycle with subsonic ammunition.

Winchester Dynapoint is the only copper plated bullet ammo that stays subsonic in rifles I have found.

CCI subsonic is very nice and lead but will not chamber in match chamber guns.

If your guns will only work with supersonic high velocity ammo, you will not be happy with the sound level as the bullet makes the sonic crack.

All things equal, shooting the same round through a LONGER barrel before it gets to your silencer translates into less wear on the silencer.

For example, the muzzle blast and report from my MkII is dramatically larger than that from a 22 rifle... and that directly translates into how hard the can is working.

Will/is the sound less from a rifle or will it be the same as the pistol?

My experience has been that, when using standard velocity ammo, the pistol usually yields quieter results because the round stays sub-sonic out of a shorter barrel. That said, a suppressed bolt-action rifle, firing sub-sonic ammunition, is about as quiet as any firearm can get.

It really depends on the caliber, ammo, weapon design, etc. As stated, if you get a bullet that's sub sonic in a pistol, but goes super in a rifle, the rifle will be much louder.

But if you take a Short AR compared to a long (16" plus barrel) AR, the gun seems louder from the shooters position. Standing off to the side... I can't tell the difference since they're both supersonic.
