Built in the USA The SOCOM556-SB2 is designed for use with a short-barrel 5.56 mm (.223 caliber) rifle. It delivers extremely low back pressure and stealthy sound attenuation in a suppressor optimized for rifle barrels of 10 inches or less. Its superior high-temperature alloy and stainless steel components are precision CNC laser-welded for strength and durability even when used in full-auto mode. Innovative internal baffling gives the SOCOM556-SB2 a significant decrease in back pressure cyclic rate and gas blowback which yields a tremendous reduction in sound and dust signatures with virtually undetectable first-round flash. The SOCOM556-SB2 also features SureFire’s proprietary Fast-Attach system which allows for easy and reliable installation or detachment from the weapon in seconds. And like every SureFire Fast-Attach model you can count on the SOCOM556-SB2 to produce minimal and consistent point-of-impact shift compared to that of an unsuppressed weapon.
