The SilencerCo AC142 ASR Muzzle Brake blends accurate recoil control with suppressor-ready convenience. Engineered for .223 Rem/5.56 NATO platforms with 1/2‑28 threads, this muzzle brake features precision-cast gas vents to minimize muzzle rise while accelerating recovery for rapid follow-up shots.
Its steel construction is heat-treated, then coated in black nitride, ensuring resistance to high heat and corrosion. As part of the ASR (Autoregulatory Suppressor Removal) system, it provides secure engagement and repeatable point-of-impact when paired with compatible ASR suppressors like Omega, Octane, or Harvester. The one-piece design is compact—approximately 2 inches long—and includes a cross-pin groove and detent hole for secure lockup.
