SRBS 556 Compact

The SRBS (Slimline Reduced Backpressure System) 556 compact is at home on 10.5-inch and shorter carbines, but is ideally suited for 11.5 to 14.5-inch barrels, where it will provide the best ratio of sound and flash reduction for its size. SRBS suppressors are the optimal solution for comprehensive signature reduction that can survive the most aggressive firing schedules and use cases. SRBS offers a substantial reduction in back pressure and combustion gases with minimal increase in cyclic rate leading to extended parts life, and improved shooter health and function.

Our hybrid Slim Reduced Backpressure System (SRBS) 5.56 Compact suppressor is ideally suited for use on short to mid-length barreled rifles with high-tempo firing schedules. Manufactured using laser bed fusion techniques and constructed of 718 Inconel, the SRBS is fully weldless, substantially reducing weight and failure points. Each suppressor ships with B&T’s Rotex-SF HUB assembly, which is compatible with all B&T Rotex flash hiders, as well as all of SureFire SOCOM flash hiders, Warcomps and muzzle brakes. The Rotex-SF HUB is machined from titanium bar stock. NATO-Spec A2 and Direct-Mount HUB assemblies are available as accessories items.
