B&T USA Suppressor A2/NATO Hub Adapter – Universal Suppressor Mount Conversion

The B&T USA Suppressor A2/NATO Hub Adapter converts suppressors with industry-standard hub threading to accept A2-style flash hiders and NATO-pattern muzzle devices. This adapter expands compatibility for shooters running multiple host firearms with A2 birdcage flash hiders or NATO-spec muzzle brakes, eliminating the need to swap direct-thread mounts or purchase additional suppressor bodies.

Machined from heat-treated steel with a durable finish, this hub adapter threads into the rear of compatible suppressors and provides a female 1/2×28 or 5/8×24 interface (verify your suppressor's hub thread pitch before ordering). Installation is straightforward—thread the adapter into the suppressor hub, torque to manufacturer spec, and mount to your A2 device. This adapter is designed for use with B&T suppressors and other hub-compatible models. Note: Suppressor use is regulated under the National Firearms Act (NFA) and requires ATF approval.
