You don't have to compromise on the performance or reliability of your suppressor just because your primary is a short-barrel rifle. The SOCOM556-SB2 is designed and engineered by the same dedicated team that produced the USSOCOM suppressor trial-winning SOCOM556-RC. The SB2’s larger bore diameter and innovative internal design deliver extremely low-back pressure and stealthy sound attenuation in a rugged suppressor optimized for rifle barrels of 10 inches or less. Its high-temperature alloys and stainless steel components are CNC laser-welded for strength and durability even when the SB2 is used in full-auto mode. Its innovative internal baffling significantly decreases back pressure, cyclic rate, and gas blowback while delivering tremendous accuracy with a minimal and consistent point-of-impact shift. It's the right tool for the job.
