SUREFIRE SOCOM MB 5.56MM 1/2X28 M4

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.
