The SilencerCo Piston in M14.5x1 LH thread pattern adapts compatible SilencerCo pistol suppressors to host pistols with metric left-hand threaded barrels, a pattern common on European handguns and their threaded-barrel variants. The piston is the heart of a Nielsen-device booster assembly, allowing a browning-action pistol's barrel to cycle reliably under the added weight of a suppressor. Precision-machined from hardened steel to maintain concentricity shot after shot, it installs in compatible booster assemblies in seconds. If your threaded pistol barrel wears this metric pattern, this is the part that brings your SilencerCo can to it.
