Surefire SFMB-556-1/2-28 SOCOM Muzzle Brake – SFMB Muzzle Brake Suppressor Adapter

Reign over recoil with the Surefire SFMB-556-1/2-28 SOCOM Muzzle Brake. It greatly reduces both recoil impulse and muzzle rise so that your weapon tracks straight back, keeping you on target for faster shot to shot recovery. Surefire’s proprietary Impulse Diffusion design minimizes side blast and rear directed concussion effects. Precision machined from U.S. mill-certified heat treated stainless steel bar stock and DLC coated for extreme durability, this model is compatible with M4/M16/AR Variants with 1/2-28 muzzle threads, and every SFMB serves as a rock solid mounting adapter for SureFire’s combat proven SOCOM Series Fast Attach suppressors.

The SFMB design incorporates multiple bearing surfaces to ensure superior suppressor alignment. Blind pilot holes at the 3 o’ clock and 9 o’clock positions enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. Blind pilot holes at the 6 o’clock position enable indexing the adapter at bottom dead center. All that’s required is a basic hand drill and appropriate drill bits.
