I have a TA31F ACOG on an A.R.M.S. QD mount on my RRA 5.56, and a Trijicon 3-9x40 AccuPoint TR-20-2G on a LaRue LT104 mount, which comes with either QD mounts or VFZ mounts which I have, since I don't remove that scope. The AccuPoint is on a dedicated hunting AR in 6.8 SPC.
I've been enormously pleased with both products and mounts. Crystal clear glass, Bindon Aiming Concept in the case of the ACOG, tritium and fiber optic illumination, and they're both built like tanks.
