SUREFIRE SOCOM FH 6.8SPC 5/8X24

The SureFire SOCOM FH 6.8 SPC muzzle device is a three-prong flash hider engineered for shooters running .277 Caliber platforms. Chambered in 6.8 SPC and threaded 5/8x24, this flash hider tackles one of the most visible problems in tactical shooting and hunting: muzzle flash. SureFire's proven SF3P design cuts flash signature by more than 99%, keeping your shooting position concealed and your shooter's night vision intact—critical advantages whether you're on the range, in low-light hunting scenarios, or training hard. The SOCOM FH is also the foundation of SureFire's Fast-Attach suppressor ecosystem, featuring precision bearing surfaces that align suppressors with rock-solid repeatability.

Built from U.S. mill-certified, heat-treated stainless steel and finished with DLC (diamond-like carbon) coating, this muzzle device resists erosion and stands up to sustained fire. The three tines are engineered to handle the stress of rapid shooting without deflection or premature wear. Every unit is inspected for concentricity and alignment before it ships, so you know the mounting surface is true—essential if you plan to run a suppressor and need consistent zero.

The 5/8x24 thread pitch is the standard for .277 platforms, making this hider a straightforward swap on existing 6.8 SPC uppers. If you're building a compact rifle or recce gun around the efficient 6.8 cartridge and want real flash reduction without compromise, the SureFire SOCOM FH delivers the engineering and track record SureFire is known for.
