The Angstadt Arms HUB to 1/2x28 Booster Assembly (AAHUBBA228) is a specialized adapter designed to allow the use of a Nielsen Device (booster) on suppressors featuring the industry-standard 1.375x24 HUB mount.
This is a critical component if you want to run a "universal" hub-mount suppressor on a semi-automatic handgun with a tilting barrel (like a Glock or SIG), as it ensures the firearm cycles reliably.
