B&T 556 Slim Line SRBS (Inconel)

B&T SRBS 556 Compact Suppressor

The Slimline Reduced Backpressure System (SRBS) 556 Compact suppressor is engineered for demanding, high-volume firing schedules where durability and performance are critical. Designed to deliver comprehensive signature reduction, the SRBS significantly lowers back pressure and combustion gases while keeping cyclic rate increases to a minimum — with just a 1.9% increase in bolt speed. The result: longer parts life, enhanced firearm function, and improved shooter health.

Optimized for short- to mid-length-barreled rifles, this suppressor is built using advanced laser bed fusion technology and constructed entirely from 718 Inconel. Its fully weldless, 3D-printed design reduces weight and eliminates traditional failure points.

The Print-X series integrates the Rotex-SF HUB adapter, fully backward compatible with any 1.375x24 TPI HUB device. Additional features include:

Bead-blasted finish

Wrench flats for easy installation

Print-X tube texturing

An updated low-flash endcap
