SUREFIRE SOCOM RC4 5.56MM BLK

Description

The SOCOM556-RC4 is SureFire’s fourth-generation 5.56mm suppressor, built for professional use on rifles that see sustained, hard use — particularly short-barreled platforms where heat, gas pressure, and muzzle signature are the hardest to manage. It is the right choice for anyone running a 5.56 rifle in conditions where reliability over a long string of fire matters more than price.

The entire body is machined and 3D-printed from U.S. mill-certified Inconel superalloy, a nickel-chromium material chosen for its ability to resist heat and erosion that would degrade lesser metals during extended automatic or semi-automatic fire. Components are joined by CNC laser welding rather than conventional assembly methods, which keeps the structure intact under the thermal cycling that short-barreled 5.56 guns impose. The Cerakote finish protects the exterior under field conditions.

SureFire redesigned the internal gas flow geometry for this generation, and the result is a 60% reduction in back pressure compared to earlier SOCOM suppressors. That reduction has direct, practical consequences: less combustion gas pushed back into the action means a cleaner-running rifle over a long session, reduced shooter exposure to propellant gases, and more consistent felt recoil impulse. The revised muzzle architecture also cuts flash signature and adds structural resistance against front-end impacts — a meaningful consideration for anyone who may contact the suppressor against hard surfaces under stress.

Mounting uses SureFire’s Fast-Attach system, which allows tool-free attachment and removal and is backward compatible with existing SureFire SOCOM Fast-Attach muzzle devices. The RC4 is optimized for use with the SF3P, FH556RC, and WARCOMP open-tine flash hiders. At 6.3 inches overall, it adds 3.8 inches to the host weapon’s length — a deliberate balance between sound management and maintaining the handling characteristics of a short rifle. Designed and manufactured in the United States.
