Pistons are a must have for proper operation of tilt barrel semi automatic pistols. This SilencerCo 1/2"x28 SN Piston is constructed out of heat treated 17-4 stainless steel. SilencerCo designed their pistons to be able to be easily changed out for use on many different platforms and calibers. Place this piston into your Neilson device/booster to allow the suppressor to move when your barrel unlocks, this makes your pistol cycle rounds and not jam. If you have a fixed barrel, then you can throw a fixed barrel spacer on this piston to keep it from moving. This piston is compatible with most series of SilencerCo suppressors. The SN mean this piston indexes off the muzzle instead of the barrel shoulder, normally this is needed for small profile barrels. Throw is piston in your suppressor for use with your Glock 43, M&P Shield, or other soft shoulder pistols.
