B&T 556SRBS Slimline SRBS Reduced Back Pressure Quick-Attach .223/5.56 Rifle Sound Suppressor | A2 NATO

The B&T SRBS (Slimline Reduced Backpressure System) 556 full size 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. While traditional suppressors will increase the cyclic rate by up to more than 30% due to back pressure, B&T's unique design increases the cyclic rate by only 4%, which ultimately reduces both fouling and wear and tear on the gun leading to extended parts life, and improved shooter health and function.

B&T's Slim Reduced Backpressure System (SRBS) 5.56mm Full-Length suppressor is ideally suited for use on short-barreled and mid length rifles and rated for sustained automatic-fire. Manufactured using laser bed fusion techniques and constructed of 718 Inconel, the SRBS is fully weldless, substantially reducing weight and failure points.

A quick attach/detach is used for compatibility with all A2 NATO flash hiders made to specifications, no need for a proprietary adapter.

NATO model suppressors come with B&T’s A2 NATO HUB assembly installed for use on A2 NATO flash hiders. Rotex-SF and Direct-Mount HUB assemblies are sold separately and easy to install adapting to operators needs.
