SilencerCo ASR 1-Port Muzzle Brake | 5/8-24 | AC2627

The SilencerCo ASR single-port muzzle brake (MFR#: AC2627) is a compact, single-port device designed to interface with SilencerCo’s ASR mounting system. It provides a quick one-hand-on, one-hand-off attachment and detachment workflow and ships with a shim set and rocksett for timing and fitment. The 1-port geometry is intended to mitigate felt recoil and muzzle climb for follow-up accuracy.

Typical applications include precision and competition shooting where controlled follow-up shots matter, and hunting scenarios where reduced muzzle rise improves shooter control. The brake is intended for use with compatible ASR mounts and related accessories.
