CMMG 1/2-28 Direct Thread HUB Mount (11DB017)

If you want the suppressor on the barrel with nothing extra in the way, this is the simple answer: a 1/2-28 direct-thread HUB mount that screws onto a 1/2-28 muzzle and accepts any suppressor with the standard 1.375-24 HUB thread. 17-4 stainless steel, nitride finish, 2.5 ounces, and 7/8-inch wrench flats so a common wrench can put it on and take it off. CMMG part number 11DB017, UPC 840442507916.

This listing is for the 1/2-28 direct-thread HUB mount only.

What It Does

CMMG built this as a straight adapter: firearm muzzle threads 1/2 x 28 on one side, suppressor HUB 1.375-24 on the other. No QD latch, no extra muzzle device — the can direct-threads onto the mount, and the mount direct-threads onto the barrel.

Size and Install

• Overall length 0.86", with 0.29" of added length once it is on the barrel.
• Diameter 1.5".
• 7/8-inch wrench flats for install and removal with common wrench sets.
• 2.5 oz.

What muzzle thread does it need?

Do I need a special wrench?

Is this a quick-detach mount?
No. It is a direct-thread HUB mount — the suppressor screws onto the HUB, and the mount screws onto the muzzle.
