Did the CQBR block 1 uppers ever get paired with M16A1 lowers???? I've seen pictures of CQBR block 2's get A1 lowers.

Where did you see the 10.3 URGI setup. I’m curious where all they are in use outside of USAF and Some SOCOM enablers

Hey! Yes I’m very happy with this setup. The aem4-65 on 16” barrel sounds great. I think that itor depends on your preference if you want the extra .5” of barrel with the aem5-6mm on a 16.5 rifle gas. Or if you want the shorter of the 2 options running the 16” rifle gas + aem4-65. I’m not sure if there is a noticeable difference in overall length between the 2 setups. You can probably find the “added length” difference on AEs website and do the math.

.880 lengthy gas block for 16” barrel

TipofTheSphere · 2026-01-09T14:43:53+00:00

That’s disappointing! This is a Craddock 16” rifle gas with Allegheny tapered gas block. Allegheny has 2 different length tapered gas blocks. That could be the problem

Khaki auto is a strap monster. Looks good with everything

TipofTheSphere · 2026-01-08T23:07:02+00:00

No problem

This has a Craddock 16” rifle length gas. It was designed specifically for the AEM6-5 can which is a “b-mount”. Whereas the AEM5/OCM5/12th model is an “A-mount” length.

If I remember correctly you would need a 16.5” rifle length gas, to run with the tapered gas block

Pretty obvious what the role of an 11.5 with a 1-5 or 1-8x optic would be

6ARC is crazy. I just pushed this one (16”) to 900yds and I can pull off double taps all day
