Angstadt Arms HUB to 1/2x28 Direct Thread Adapter - 17-4 Stainless Black Nitride

The Angstadt Arms HUB to 1/2x28 Direct Thread Adapter is a precision-machined thread adapter that lets you mount any HUB-spec (1.375x24) suppressor directly to a barrel threaded 1/2x28, with no quick-detach mount or booster required. It is a clean, low-profile solution for pistol-caliber carbines, AR-pattern rifles, and any host firearm chambered in a caliber that uses the common 1/2x28 thread pitch.

The adapter is machined from 17-4 stainless steel and finished in a corrosion-resistant black nitride coating, so it is built to handle the heat, carbon, and pressure of regular suppressor use. It measures 1.55" in diameter, adds only about 0.2" of overall length to the suppressor stack, and weighs just 2.5 oz. Proudly made in the USA by Angstadt Arms.
