SilencerCo ASR Muzzle Brake - Single Port
SILENCERCO ASR SINGLE PORT MUZZLE BRAKE
The SilencerCo ASR Single Port Muzzle Brake threads onto your barrel and serves as the host-side interface for SilencerCo's ASR (Active Spring Retention) quick-attach suppressor mounting system. It is compatible with both the standard ASR mount and the Nano ASR mount, covering a wide range of SilencerCo suppressors. The single-port design redirects propellant gases to reduce felt recoil and muzzle climb while keeping overall length shorter than SilencerCo's 3-port ASR muzzle brake. Attachment and detachment of a compatible suppressor is one-handed and tool-free. Available in 5/8x24 for .30 caliber hosts and 1/2x28 for 9mm and 5.56 hosts.
The ASR mounting system comes standard on several current SilencerCo suppressors and is available as an optional accessory on others. See the full compatibility list below to confirm which mount your suppressor uses.

SILENCERCO ASR MUZZLE BRAKE - SINGLE PORT
This single-port muzzle brake is compatible with the new SilencerCo Nano ASR mount and the original ASR mounting system. The ASR mounting system comes standard on the Omega 300, Chimera 300, Omega 36M, Hybrid 46M, Saker ASR and Specwar family of suppressors. It is an optional accessory for the Hybrid, Saker (discontinued) and Harvester 338 suppressors. The Nano ASR mount is an optional accessory for the Harvester 300, Omega 9k / 45k, and Octane series of suppressors. Both mounts offer one hand-on, one hand-off attachment/detachment, and the 1-port design effectively reduces felt recoil and muzzle climb in a shorter overall package.
