SureFire SOCOM RC4 Low Back Pressure 5.56mm Inconel Suppressor - Black

SureFire SOCOM RC4 Low Back Pressure 5.56mm Inconel Suppressor - Black

The SureFire SOCOM556‑RC4 represents the newest evolution of the world’s premier 5.56mm combat suppressor. Designed for professional end‑users who demand absolute reliability in the harshest environments, the RC4 delivers a combination of extreme durability, ultra‑low back pressure, and industry‑leading flash suppression unmatched by any other 5.56mm suppressor on the market.

Constructed entirely from U.S. mill‑certified Inconel superalloy, the RC4 withstands the brutal heat and erosion of sustained fire—even on short‑barreled rifles. Its hybrid construction of machined and 3D‑printed aerospace‑grade components, joined by precision CNC laser welding, ensures structural integrity that outlasts and outperforms conventional suppressors.

SureFire’s fourth‑generation flow dynamics reduce back pressure by 60%, dramatically cutting toxic gas blowback, improving weapon reliability, and delivering noticeably smoother recoil. The RC4’s new muzzle architecture significantly reduces frontal flash signature and enhances durability against impacts—providing a real tactical advantage in low‑visibility or stealth‑critical engagements.

The suppressor mounts using SureFire’s proven SOCOM Fast‑Attach® system, allowing rapid, tool‑less attachment and full backward compatibility with millions of existing SureFire muzzle devices already in service. Optimized for 10.3" and longer barrels, the RC4 adds only 3.8 inches to overall weapon length, maintaining excellent handling characteristics.
