Thanks for your input. After you filed, any issues coming loose?I had to do some filing in order to get that mount to fit the optic. I love the MPS when I'm shooting--I pick it up more quickly than others which I believe is because of the emitter being at the top.
My goal was to stay away from that brand but it may be the only optionI use chpws adapter plate for MPS on my sig p320 pro cut slide with suppressor height sights, with cowitness and no adjustments to the plate needed. Very satisfied. you might get a good deal on the plate with sales going on now.
