Description
Sometimes the simplest mounting setup is the right one, and it does not get much simpler than direct threading your can straight onto the barrel. The CMMG Zeroed 1/2×28 Direct Thread HUB Mount screws into any suppressor with the industry-standard 1.375×24 HUB thread and lets you run it on hosts with 1/2×28 muzzle threads. That covers a huge slice of the market, from 5.56 ARs to 9mm PCCs and plenty of rimfire hosts, so odds are good you already own something this bolts right up to.
Why the Zeroed HUB Mount Earns a Spot in Your Range Bag
Direct thread mounts like this one are popular for a reason. There is no muzzle device to time, no locking collar to fuss with, and fewer parts that can work loose or throw off alignment. The mount adds barely any length to your suppressor, which keeps the whole package compact and balanced. It is a great fit for bolt guns, precision rigs, and any host where you plan to leave the can mounted for a full range session rather than hot-swapping between rifles.
Built Like the Rest of the Zeroed Line
CMMG machines this mount from stainless steel and gives it a nitride finish, the same treatment found on their Zeroed suppressors. Nitride hardens the surface and shrugs off carbon, heat, and corrosion, so the mount holds up to real use instead of looking rough after a few hundred rounds. The 7/8 inch wrench flats work with common hand tools, which makes installing or removing the mount from your suppressor quick and painless when it is time to clean or swap thread pitches.
Pairing the CMMG Zeroed Mount With Your Suppressor
Because the 1.375×24 HUB pattern has become the standard across most of the suppressor industry, this mount is not limited to CMMG cans. If your suppressor takes HUB mounts, this will thread right in. Keep one dedicated to your 1/2×28 hosts and you can move your can between rifles without buying a full mounting system for each one. It is a small part that adds a lot of flexibility to a suppressor setup.

Frequently Asked Questions
Will the CMMG Zeroed HUB Mount work with suppressors from other brands?
Yes. This mount uses the industry-standard 1.375×24 HUB thread pattern, which most modern suppressor makers have adopted. As long as your can accepts HUB mounts, this will thread in whether it is a CMMG Zeroed or a suppressor from another manufacturer.
What firearms is the 1/2×28 thread pitch used on?
1/2×28 is one of the most common muzzle thread patterns out there. You will find it on most 5.56 AR-15 barrels, the majority of 9mm pistols and carbines with threaded barrels, and nearly all threaded .22 LR hosts. Just confirm your barrel's thread pitch before ordering, since some calibers use 5/8×24 or other patterns instead.
Do I need any special tools to install the Zeroed direct thread mount?
No proprietary tools required. The mount has 7/8 inch wrench flats, so a standard wrench handles installation and removal from your suppressor. Once the mount is seated in the can, you simply thread the whole assembly onto your muzzle by hand and snug it up.
Is a direct thread mount better than a quick-detach system?
It depends on how you shoot. Direct thread keeps things lighter, shorter, and simpler with fewer parts to wear or come loose, and it tends to be very consistent for accuracy. QD systems shine when you are moving one suppressor between several rifles frequently. For dedicated hosts and precision work, direct thread is hard to beat.
