The advanced SureFire SFMB-338-3/4-24 muzzle brake, which fits 8.60 mm (338 caliber) rifles with 3/4-24 muzzle threads, greatly reduces both recoil impulse and muzzle rise and features neutral porting that loads bi-pod legs evenly. Its patented impulse diffusion design minimizes side blast and rear-directed concussion effects. The SFMB-338-3/4-24 also serves as a rock-solid mounting adapter for 338 caliber SureFire SOCOM Series Fast-Attach suppressors. Precision machined from US mill-certified heat-treated stainless steel bar stock - including high-precision single-point cut threads for optimum thread interface - the SFMB-338-3/4-24 muzzle brake is given a black Ionbond DLC coating to provide maximum protection under harsh environmental conditions and to facilitate cleaning even after extreme use. When used in conjunction with a SOCOM Series suppressor, the patent-pending design of the SFMB-338-3/4-24 provides multiple bearing surfaces to ensure superior suppressor alignment. A rear labyrinth seal minimizes potential carbon build up in the indexing system and facilitates suppressor removal after extended firing. All SureFire SOCOM Series muzzle brakes have blind pilot holes at the 3 and 9 o'clock position to enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. They also have blind pilot holes at the 6 o'clock position to enable indexing the adapter at bottom dead centre, and to pin-and-weld on short-barreled rifles. All that is required is a basic hand drill and appropriate drill bits. SureFire muzzle brakes are individually inspected for concentricity and alignment, and each is covered by SureFire's no-hassle guarantee.
