Silencerco Piston Kit

Silencerco Piston Kit

The Silencerco Piston Kit was designed to offer the most common thread pitches in a single package. 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.

Includes: .578×28, 1/2×28, 9/16x24RH, M13.5LH, M16x1LH
