B&T SD-140020 | NATO/A2 HUB Adapter | 1.375×24

The B&T SD-140020 NATO HUB is a suppressor attachment adapter designed to interface with 1.375x24TPI HUB-compatible suppressors and A2-style flash hiders. It is constructed from stainless steel and finished in black Cerakote for corrosion resistance and consistent appearance. The adapter uses a gate lock and ratchet system to provide redundant retention and precise fitment, and it can be secured semi-permanently using thread-locking compounds if desired. This HUB follows the same NATO-style attachment concept adopted by allied forces for robust field use.
