I'm trying to manufacture a horizontal wall rack for my Bushmaster. My plan is for two mounted brackets to cradle the rifle at the delta ring and the receiver extension right next to the castle nut.

To complete the design, I need to know the maximum diameter of the delta ring and of an LMT (I believe MIL-SPEC) receiver extension. Unfortunately, I don't own a caliper. Can anyone give me a hand?

1.180 is the comercial diameter and 1.170 is the mil-spec.

Thanks for the quick response!

One down (receiver extension) and one to go (delta ring).

Come on guys, surely someone out there has a caliper and two minutes to spare.

According to my calipers the delta ring is 2.100" at the wide end.
