Designed for professionals who operate in high-risk, high-round-count environments, the RC4 delivers unmatched durability, dramatically reduced back pressure, and industry-leading flash suppression in one compact SOCOM Fast-Attach package. Constructed entirely from U.S. mill-certified Inconel superalloy, the RC4 is made to endure the brutal heat and erosion of sustained 5.56mm fire - even on short-barreled rifles. Its advanced combination of precision machining, 3D-printed aerospace-grade components, and state-of-the-art CNC laser welding creates a suppressor built for extreme structural integrity. When others fail, the RC4 keeps running. Signature reduction is survival. The RC4's redesigned muzzle geometry dramatically improves gas flow and significantly reduces flash - from the first round to the last, even under extreme heat. The reinforced front end increases durability against impact while delivering the lowest visible flash in its class. Stay concealed. Stay dominant. SureFire's revolutionary low-back-pressure design reduces back pressure by up to 60% compared to conventional suppressors. The SOCOM556-RC4 features the battle-proven SOCOM Fast-Attach system for lightning-fast installation and rock-solid lockup - no tools required. Backward compatible with millions of SOCOM Fast-Attach flash hiders already deployed worldwide, it integrates seamlessly into existing setups.
