Running a HUB-pattern suppressor on a .45 ACP pistol or another host with .578×28 muzzle threads? This is the piece that makes it happen. The CMMG ZEROED HUB Mount is a direct thread adapter that converts a .578×28 muzzle to the 1.375×24 HUB standard, which has become the common language for most modern suppressor bodies. Thread it into your can, spin the whole setup onto the barrel, and you are done. No proprietary muzzle devices, no extra parts to track down.
CMMG builds the ZEROED line in-house in Missouri, and this mount carries the same no-nonsense approach as the rest of the family. The black nitride finish hardens the surface and resists corrosion and carbon buildup, which matters on a part that lives right at the muzzle where fouling is heaviest. At roughly two ounces, it adds next to nothing to the front of your setup, and the compact profile tucks neatly inside most HUB suppressor bodies. Direct thread mounting also tends to give you the most consistent point of impact from session to session, since there is no locking mechanism to introduce play.
The .578×28 pitch is the go-to threading for .45 ACP hosts, so this mount is a natural pick for threaded 1911s, Glock 21s, HK45s, and similar pistols wearing a suppressor-ready barrel. Pair it with a HUB-compatible can like CMMG's own ZEROED 46 or 36, or any other suppressor with a 1.375×24 rear thread, and you have a clean, secure interface between pistol and silencer. If you run multiple hosts with different thread pitches, CMMG offers ZEROED HUB mounts in other patterns too, so swapping your suppressor between guns is as easy as swapping mounts. Simple part, does its one job well, and does it without drama.
It fits any suppressor with the industry-standard 1.375×24 HUB rear thread pattern. That covers CMMG's own ZEROED line as well as HUB-compatible cans from most major suppressor makers. If your can accepts interchangeable HUB mounts, this adapter will thread right in.
.578×28 is the standard thread pitch for .45 ACP pistols. Threaded barrels for the 1911, Glock 21, HK45, FNX-45, and similar handguns almost always come in this pattern. Double-check your barrel's thread spec before ordering, since some hosts use other pitches.
No proprietary tools are required. The mount threads into the back of your HUB suppressor and then the whole assembly spins onto the barrel by hand, with a standard wrench used to snug things up. It is one of the simplest mounting systems out there.
Yes, direct thread mounts are known for consistent point of impact because there is no quick-detach mechanism to introduce play. As long as the mount is properly torqued to the barrel, your suppressor returns to the same position every time. Just check it periodically during long range sessions, as any threaded attachment can loosen with heat and vibration.
