Overview

Built for shooters using SilencerCo ASR Mounts, this single-port muzzle brake is intended to simplify attachment and removal while helping reduce felt recoil and muzzle climb. Its 5/8"-24 thread pattern and steel construction make it a straightforward option for compatible 30 caliber setups, including 7.62x39mm applications listed in the product data. The included shim set and Rocksett support installation, though the brake’s single-port design reflects a practical, purpose-driven approach rather than a more aggressive multi-port setup.

Considerations & Trade-offs

  • Designed around SilencerCo ASR mounts, so it is not a universal muzzle device for every rifle setup.
  • The single-port design is focused on recoil and muzzle-climb reduction, but it does not add the broader functionality of a multi-port brake or suppressor-ready mount on its own.
  • It is specified for 5/8"-24 threads and 7.62x39mm sizing, so compatibility depends on matching barrel threads and application.
  • Installation includes a shim set and Rocksett, but proper setup still requires attention to alignment and thread compatibility.
