The piston is part of the Nielson device that moves and allows semi-automatic cycling for unlocking pistol barrels. Throw a Fixed Barrel Spacer on for fixed barrel applications. SilencerCo pistons have female threading that attaches to our SilencerCo threaded barrels. The 1\/2X28 SN Piston will index on the muzzle of the barrel instead of the shoulder.
