Yhm Hub Direct Thread Mnt 5/8"-32
The Yankee Hill Machine Hub Direct Thread Mount is a precision threaded adapter that converts HUB-compatible suppressors to direct thread mounting on your barrel. If you're running a HUB suppressor and want the simplicity and security of direct threading—no separate mounts or tools required—this adapter lets you swap your existing HUB mechanism for a clean, minimal interface. It's built tough from 17-4PH heat-treated steel with black oxide finish, designed to handle the heat and pressure of suppressed fire without compromise.
Installation is straightforward: remove your current HUB mount from the suppressor, thread this adapter on using a 3/4" open end wrench, then thread the suppressor directly onto your barrel. The .45 caliber bore accommodates standard rifle and pistol rounds, and at just 1.7 ounces it won't add unnecessary weight to your setup. Whether you're running subsonic hunting loads, magnum rifle rounds, or pistol calibers, this adapter gives you the flexibility to use your suppressor across multiple platforms without swapping mounts.
Yankee Hill Machine has earned trust in the suppressor community for no-nonsense engineering and reliable performance. This adapter is a smart choice if you want to streamline your suppressor system and reduce the parts hanging off your barrel.
