SCO PISTON KIT

SilencerCo Piston Kit, Includes 1/2X28, .578X28, 13.5X1 LH, 16X1 LH, 9/16X24 AC728

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.
