B&T SRBS 556 Full Size

The SRBS (Slimline Reduced Backpressure System) 556 Full Size suppressor provides reliable signature reduction for rifles in demanding conditions. It minimizes backpressure and combustion gases while keeping cyclic rate increases low. This design improves rifle performance, extends parts life, and supports healthier, smoother shooting.

Our hybrid SRBS 5.56 Full-Length suppressor works best on short- to mid-length barrels, even during high-tempo firing schedules. B&T manufactures it using advanced laser bed fusion techniques and 718 Inconel, which ensures strength while keeping the suppressor fully weldless. This design reduces weight and eliminates common failure points. Each suppressor comes with a Rotex-SF HUB assembly, compatible with all B&T Rotex flash hiders as well as SureFire SOCOM flash hiders, Warcomps, and select muzzle brakes. B&T machines the HUB from titanium bar stock for improved durability. Users can also opt for NATO-Spec A2 or Direct-Mount HUB assemblies as accessories.

The SRBS 556 Full Size suppressor comes fully HUB-compatible (1.375×24 TPI) and is rated for full-auto operation with no barrel length restrictions. It is an excellent choice when shooters require reduced backpressure without compromising performance.
