Armaspec HUB Thread Adapter 1-3/8x24 to 0.9x24 Stainless Steel Black

The Armaspec HUB Thread Adapter is a precision-machined stainless steel mounting interface that converts a 1-3/8x24 external muzzle thread pattern to a 0.9x24 internal Bravo-style suppressor interface. Finished in a low-glare black coating, this adapter lets shooters run common Bravo-pattern silencers on hosts threaded in the larger 1-3/8x24 pattern without re-barreling the host.

Designed for rifle and pistol hosts running 1-3/8x24 external threads, the HUB Thread Adapter accepts any suppressor or mount that uses the 0.9x24 internal thread, giving users a clean, factory-spec mating surface. The compact adapter installs in seconds and is machined from stainless steel for long service life under repeated mount and dismount cycles. Whether you are building a dedicated suppressor host or want to keep an existing 1-3/8x24 barrel and add a Bravo-pattern can, this adapter delivers a straightforward and reliable solution.
