With a 22mm width, this heavy-duty 4140 heat treated gas block mount is intended for the larger items that you might mount.

The other NATO spec, 21mm, will be out soon in 6061 Aluminum.

Please make sure to measure your attachment before ordering.

My latest invention-hooks onto your gas block so you can mount a bipod, hand guard, flashlight, laser, etc.. We all know the barrel mounts affect accuracy and the lower hand guard mounts take up valuable real estate.
