Does not work with a gen 1.5 mro, otherwise functional magnifier - Trijicon MRO HD 3X Red Dot Sight Magnifiers

eems like a fine product overall, I like the small form factor and effective QD mount. Easy to flip in and out of sight line. However, it is NOT compatible with a gen 1.5 MRO (serial number 89,000+ with 1x magnification or factory refurbished). Bought one to try with my older MRO, and the dot is a blurred line through the entire diopter adjustment range. Likely also will not work with gen 1 (SN below 89,000) MRO. No comment on durability or other features.

Also does not work with an Aimpoint T2 or a Primary Arms Micro Dot, and will not mount properly if directly mounted over a rear Magpul plastic iron sight. YMMV.

Side note, but I'm a little disappointed in Trijicon for outsourcing the manufacture of the magnifier to China. Boo.
