SilencerCo

This 3-port muzzle brake is compatible with all SilencerCo ASR Mounts. It offers quick and easy one-hand-on, one-hand-off attachment and detachment. The 3-port design effectively reduces felt recoil and muzzle climb. Each ASR muzzle brake comes with a shim set and rocksett for easy application.

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.

This part is used in conjunction with pistons on firearms with fixed barrels, such as rifles and submachine guns. This piece is used in place of the piston booster spring.
