SF 5.56 FH 1/2X28

The advanced SureFire SFMB-556-1/2-28 muzzle brake, which fits M4 / M16 weapons and variants with 1/2-28 muzzle threads, greatly reduces both recoil impulse and muzzle rise so that the weapon tracks straight back to keep you on target for faster shot-to-shot recovery. Its patented Impulse Diffusion design minimizes side blast and rear-directed concussion effects. The SFMB-556-1/2-28 also serves as a rock-solid mounting adapter for SureFire SOCOM Series 5.56 mm Fast-Attach1 suppressors, the SOCOM556-RC model having placed first in the most extensive and rigorous suppressor testing ever conducted by US Special Operations Command. 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-556-1/2-28 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-556-1/2-28 provides multiple bearing surfaces to ensure superior suppressor alignment. A rear labyrinth seal minimizes potential carbon buildup 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 ammunit
