Just right - Trijicon Mounts for MRO 2.0 MOA Adjustable Red Dot Sight

Not too spendy, excellent machining and fits the MRO perfectly. Lined up with the red dot exactly on top of the front post of my magpul sights--only a couple clicks to zero. Well built--about the only thing missing is a quick release, but that is just going to push the price up. Comes with the 4 screws to mount to the MRO and an alan key. Excellent, simple, just right.
