Excellent product - Unity Tactical FAST FTC Omni Mount

I use this magnifier mount alongside an Eotech exps3 that is mounted on a Unity FAST riser mount. If you install the magnifier with the plate that is also installed on the standard Eotech flip-to-side mount it will be misaligned when flipped up and will smack into your the bottom of the mount when flipped to center. You need to take that plate off and install the magnifier with short screws instead of the long ones for that plate. I didn't know this prior to purchasing the mount and had to order a set of short screws from Eotech so that I could properly mount it without the plate. I also am pretty sure you NEED a FAST riser for your eotech holographic sight for everything to line up when this is installed properly.
