SILENCERCO 13.5Mx1 LH XL Piston (AC626)

The SILENCERCO 13.5Mx1 LH XL Piston (AC626) is easily changed out to allow you to adapt your favorite SilencerCo pistol to a variety of host weapons. Piston is 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 the SilencerCo threaded barrels.

XL pistons are for firearms where the silencer requires additional length between the threaded barrel and the silencer.

This piston is compatible with the SilencerCo Octane, Osprey, Hybrid 46, and Omega K Series suppressors.
