Product Description

"SilencerCo pistons were designed to be easily changed for different host firearms or calibers. Pistons are built with 17-4 stainless steel, then heat-treated for maximum durability. 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. This is used on small profile pistol barrels with an inadequate shoulder diameter."
