These pistons were designed to be easily changed for different host firearms or calibers. Pistons are built with 174 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. A Fixed Barrel Spacer (not included) is required for for fixed barrel applications, such as pistol caliber carbines or any pistol where the barrel doesn’t unlock during the cycling process. SilencerCo pistons have female threading that attaches to threaded barrels. 1X piston included.
