Kevin, yeah from a service perspective and fit, finish, and function of the parts Aero has been spot on in my experience. I don't feel like anything is lacking at all. The upper was free to me but I would have to echo the same sentiment had I paid for it. This thing is just really great.

As far as sub moa, I wasn't really paying a ton of attention to groupings. Focused more on function really. I sighted it "close enough" and sat back watching the girl run it mostly which was the intent of the range trip. I can say that I did sort of bear down on the last full magazine and that 30 round group was inside 2.5 inches at 50 yards.

There's more in it, but the next trip I'll use a spotting scope with whatever setup I land on as far as an optic and focus more from a precision perspective.

Gost, thanks for the CMC endorsement. From what I can tell guys are pretty pleased with their stuff.
