Mfg Item #: AC1756
Our 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.
XL pistons are for firearms where the silencer requires additional length between the threaded barrel and the silencer.
The 1/2 X 28 SN (AC1756) 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.
