Description

The SureFire SOCOM556-RC4 is a full-Inconel 5.56 suppressor built for sustained professional use. Its redesigned S-curve gas flow geometry delivers roughly four times better flash reduction than the RC3 while maintaining the low back pressure and sound reduction the SOCOM line is known for.

Up to 60% back-pressure reduction keeps your rifle cleaner, runs cooler, and cycles more reliably under high-volume fire. At 6.3 inches and 17 ounces, it mounts and removes in seconds via SureFire’s Fast-Attach system, and it’s backward compatible with all existing SureFire SOCOM Fast-Attach muzzle devices.

Features & Benefits

• Up to 60% back-pressure reduction compared to unsuppressed fire – less gas in the action means a cleaner rifle, better reliability, and reduced felt recoil
• Full Inconel superalloy construction (U.S. mill-certified) withstands the heat and erosion demands of sustained 5.56 fire without degrading performance
• S-curve gas flow geometry provides roughly 4x better flash signature reduction vs. the RC3, optimized for both day and night operations
• Fast-Attach mounting system locks and removes tool-free in seconds; backward compatible with all existing SureFire SOCOM Fast-Attach muzzle devices
• Cerakote finish over Inconel for heat and corrosion resistance in field conditions
• Optimized for 10.3-inch and longer 5.56 barrels; rated for semiautomatic and full-auto fire
• Available in Black and Flat Dark Earth (FDE) to match your rifle setup
