The RBS SQD suppressor features a Reduced Backpressure System (RBS) tailored for SMG and rifle calibers, utilizing a flow-thru design to minimize backpressure and enhance gas management. This innovative system reduces gas re-entry into the firearm, mitigating wear and enhancing operation by containing toxic combustion byproducts. Its compatibility is specific to B&T 45 3-Lug mounts and similar designs, excluding HK / Traditional 9mm 3-Lug barrels and muzzle devices. Benefits include reduced firearm wear, a softer shooting experience, and lower exposure to harmful gases.
