Reviews & Ratings for AIM Sports Inc Trijicon MRO Mount Absolute CO-Witness — 1 review — Page 1

Ok, so I bought a Midwest Industries QR mount for my MRO, but it's backordered for a couple months everywhere I looked, so I bought one of these to get by. Seems solid, comes with 2 sets of screws (which is nice), and mounted up easy enough. HOWEVER, the bolt on the side for mounting to the top rail is a STRANGE size that doesn't fit any standard socket. I tried Standard and Metric, it would NOT fit any of them. 11mm, 7/16 and everything close to that, none of them would fit. So, you can't torque this with a Wheeler torque wrench or what have you. I ended up using some slip joint pliers I have with nylon teeth so I wouldn't mar the finish. I don't think I would recommend this as a primary mount, but as a stop gap while I wait for one that's on backorder, it will suffice.
