Pistons are a must have for proper operation of tilt barrel semi automatic pistols. This SilencerCo 1/2"x28 XL 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 XL means this piston is extended to give additional length between the threaded barrel and the shoulder. This helps give more clearance for the recoil rods or slide and makes it so the pistol does not go out of battery.
