Pistons are needed for proper operation of tilt barrel semi-automatic pistols so they do not jam. This SilencerCo 1/2"x28 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. And it is for use in semi-automatic pistols with a caliber of 9mm or smaller.
