B&T Firearms SD-145582 Adapter Direct Thread HUB Fits 1/2"x28 Black

The B&T Firearms SD-145582 is a direct-thread adapter hub designed for shooters running suppressed setups with 1/2"x28 threaded barrels. If you're building a modular sound suppressor system or need a reliable interface between your barrel and suppressor, this adapter provides a solid connection point without relying on quick-detach mechanisms. It's finished in black and built to B&T's standards—the kind of no-nonsense component you'd expect from a Swiss precision firearms manufacturer.

Direct-thread adapters are popular with shooters who want a permanently attached suppressor interface, eliminating any play or rattle between suppressor and barrel. This hub works with any 1/2"x28 threaded barrel, making it compatible with most modern rifle platforms chambered in common calibers. Whether you're setting up a precision rifle for the range, a hunting rig that needs to stay quiet, or an AR-pattern gun, this adapter fills a straightforward role in your suppressor mounting strategy.

B&T engineered this component to mate reliably with their suppressor systems and other quality cans that accept standard 1/2"x28 threads. It's a small piece, but it's the foundation of a clean, repeatable suppressor zero—something that matters if you're chasing accuracy or trying to minimize hearing damage in the field.
