Angstadt Arms HUB to 1/2x28 Booster Assembly

The Angstadt Arms HUB to 1/2x28 Booster Assembly is a suppressor accessory designed to enable HUB-compatible suppressors (1.375×24 TPI) to function with semi-automatic pistols that utilize tilting or reciprocating barrels. This booster assembly, also known as a Nielsen device, installs at the rear of a compatible suppressor and allows it to be mounted directly to standard 1/2x28 threaded pistol barrels.

The assembly includes the necessary internal components to support proper cycling and operation when using a suppressor on handgun platforms. Designed for compatibility across a range of HUB-pattern suppressors, it provides a modular solution for adapting rifle-rated suppressors for use on pistols where applicable.
