B&T Direct Thread HUB Adapter, 1/2×28

The B&T Direct Thread HUB Adapter lets a B&T HUB-compatible suppressor mount to a standard 1/2×28-threaded muzzle (B&T part no. SD-145582). It is a lightweight adapter rather than a quick-detach mount, threading directly onto the barrel the same way a standard flash hider or brake would. B&T builds this for shooters who already run a HUB-pattern suppressor and want a simple, direct-thread option instead of a QD mount on a specific rifle or pistol. It is a focused, single-purpose accessory rather than a complete mounting system.

Key Specifications

• It is threaded 1/2×28, matching common 5.56/.223-pattern muzzle threads.
• It is a direct-thread design rather than a quick-detach mount, threading straight onto the barrel.
• It is built as a lightweight HUB adapter, keeping added weight at the muzzle to a minimum.
• Because it threads on rather than locking with a quick-detach lever, it typically weighs and costs less than a QD mount.

Frequently Asked Questions

Is this a quick-detach mount? No, this is a direct-thread adapter. It threads onto the muzzle rather than locking and unlocking with a quick-detach lever.

What thread pitch does this adapter use? It is threaded 1/2×28, a common thread pitch for 5.56/.223-pattern rifles.
