Evolution at the Speed of Sound. The SureFire SOCOM556-RC4 is the world's finest 5.56mm fighting suppressor, delivering the ideal combination of extreme durability, low-back-pressure performance, and industry-leading flash reduction—wrapped up in a compact SOCOM Fast-Attach® package.
Built entirely from U.S. mill-certified Inconel superalloy, the SOCOM556-RC4 ensures uncompromising resistance to the brutal heat and erosion of sustained 5.56mm fire, even with short-barreled rifles. Its combination of machined and 3D-printed, aerospace-grade components, and cutting-edge CNC laser welding, guarantees the unmatched structural endurance that SureFire suppressors are known for around the world. The RC4's all-new muzzle design improves flow and significantly reduces flash for superior signature reduction, providing the operator with a meaningful edge in stealth-critical engagements. SureFire's flash suppression performance is the finest in the industry, from the first round to subsequent rounds, even when the suppressor is hot. The beefed-up muzzle also improves durability against front-end impacts. The RC4 will keep performing long after others fail.
SureFire's innovative low-back-pressure design reduces back pressure by a staggering 60% compared to conventional suppressor designs. That means less toxic gas in shooter's face, a cleaner-running firearm, less wear and tear on parts, and noticeably better recoil management. The SOCOM556-RC4 mounts via our proven Fast-Attach system, ensuring lightning fast and secure attachment and removal with no tools required. That means it is backward compatible with millions of SOCOM Fast-Attach flash hiders already in the field.
Proudly designed in the U.S.A., the SOCOM556-RC4 is a suppressor without equal. It thrives on the modern battlefield and delivers the durability and performance professionals demand.
