Surefire Fa Hub 556 3/8-24 Socom

The Surefire Fast-Attach Hub 556 3/8-24 Socom is a precision-engineered muzzle device adapter designed for operators who demand reliable mounting solutions on modern tactical rifles. This threaded hub serves as an interface between your rifle's barrel and Surefire suppressors, flash hiders, or muzzle devices, enabling rapid attachment and detachment without tools. Built for 5.56mm NATO platforms with 3/8x24 TPI threads, it's essential gear for law enforcement, military, and civilian shooters running Surefire's modular suppressor ecosystem.

Surefire's Fast-Attach system operates on a robust indexing mechanism that ensures zero baffle strike and consistent suppressor alignment shot after shot. The hub itself is precision-machined from high-strength steel with a nitride finish, providing corrosion resistance and durability in field environments. At just 0.44 pounds, this compact adapter (2 x 2 x 4 inches) adds negligible weight to your rifle while maintaining the timing accuracy critical for suppressor performance. The 3/8x24 TPI thread pitch matches standard AR-platform barrels, allowing seamless integration with existing Surefire suppressors like the SOCOM series.

Operators with suppressed 5.56mm rifles—whether in duty, training, or precision shooting roles—benefit most from this proven mounting standard. The Fast-Attach hub is ideal for rifles that rotate between multiple Surefire accessories or require rapid suppressor changes in tactical environments. Installation is straightforward: thread the hub directly onto your rifle's barrel at the existing 3/8x24 threads, then lock your Surefire suppressor or muzzle device onto the hub's indexing lugs. This adapter is compatible with all Surefire Fast-Attach suppressors and flash hiders, ensuring long-term versatility across your tactical platform.
