B&T is excited to introduce you to the next evolution of suppressors - their Reduced Backpressure System (RBS) line of SMG and rifle caliber suppressors. This revolutionary flow-thru suppressor design features a low-pressure chamber design to absorb a substantial amount of gas, thereby reducing back pressure. This significantly minimizes, and in some cases, eliminates excess gas pressure at the charging handle and ejection port locations, making the RBS a top choice for submachine guns, assault rifles and machine guns. B&T's latest commitment to suppressor innovation is their Reduced Backpressure System line of suppressors (RBS). RBS technology is a giant leap forward in reducing the amount of back blast to the shooter that is composed of carbon monoxide, ammonia hydrogen cyanide, as well as the content and composition of metals in the dust emitted from various small arms weapons systems during prolonged firing by the shooter. All RBS Suppressors feature a low-pressure chamber design to absorb a substantial amount of gas, thereby reducing back pressure.
