I was actually thinking about going with a non-QD mount and run the 45º XS sights to try and shed as much weight as possible.
Any vendors you normally buy from for the Aero Precision? I've honestly always just bought QDs for everything from LaRue or GG&G or ADM direct (when they were the only ones with a 35mm option for an IOR scope).
I just checked a few places....and Aero's site. They don't list the height of the center of the mount though. Got an email in now to try and figure that out. Looks like they only offer one height and I'm guessing it's going to be standard 1.5"ish for ARs. I'm trying to go a lot lower (around 1") so I may just settle for a set of low rings.
