SureFire HUBFA556BK 5.56mm 1 3/8"x24 Heat Treated 17-4 Stainless Steel Nitride Black

The SureFire Fast-Attach Hub suppressor mount allows easy conversion of 1 3/8-24 thread-pattern HUB suppressors and accessories to QD for use with SureFire SOCOM Fast-Attach muzzle devices. Slide the Hub over the SureFire muzzle adapter, indexing on the built-in slot, and secure the lock ring at the base.

The Fast-Attach Hub is precision-machined with the same dimensions and tolerances as our combat-proven suppressor back section to ensure the proper fit with SOCOM muzzle devices. It is manufactured of stainless steel in the U.S.A. and black nitride-coated for unmatched durability and long service life.

The Fast-Attach Hub is not an NFA device and is available wherever SureFire products are sold, without any of the restrictions associated with suppressors.
