SilencerCo ASR Muzzle Brakes

SilencerCo ASR Muzzle Brake Details

The SilencerCo ASR Muzzle Brake serves two functions on one device: it tames recoil and muzzle rise when you're running unsuppressed, and it acts as the quick-detach mount interface when you're ready to thread a SilencerCo ASR-equipped suppressor on top. One muzzle device, two roles, no compromise on either.

Pick the right brake by matching two things: caliber (the brake bore) and thread pitch (matches your barrel).

The ASR Mount System: Alpha, Bravo, Charlie

Bravo ASR — original ASR rifle cans (Omega 300, Hybrid 46). Also HUB-compatible via separate Bravo Direct Thread Mount.

Charlie ASR — current-generation rifle and modular cans (Saker ASR 556 / 556K / 762, Chimera 300, Omega 36M, Hybrid 46M).

Caliber and Thread Pitch

The bore of the brake has to match your caliber. The thread pitch has to match your barrel. Common configurations:

• 5.56 NATO — 1/2x28
• .30 cal (.308, 6.5 Creedmoor, 6mm ARC, 6.5 Grendel, 7.62x39, .300 BLK, etc.) — 5/8x24
• .338 — 5/8x24 or 3/4x24
• .45 — 5/8x24 LH

11 total thread pitches across the caliber range. Match the variant to your build.

Installation and Timing

The brake ships with a precision shim set for timing alignment. Torque to spec, time the brake so the porting orientation matches your shooting position (most users prefer top ports off-axis for muzzle rise control), and you're ready to mount the suppressor. The QD interface uses a ratcheting cam-lock mechanism — twist the suppressor on, rotate to lock, no extra tools required.
