Mpo-f pistol optic - Meprolight MPO-F 1x 0.95x0.7in Reflex Red Dot Sight

I put this red dot on my Spring Field Echelon that I edc (every day carry). It has been about 6 months and other than changing the battery once, it has worked great. The optic sits low and co-witness with factory sights but the light sensor was blocked by the slide. I also train with my edc, so this optic has seen at least 1k rounds of 9mm. It came with several screw options, so installation was easy. Those options also made it capable to fit my Smith & Wesson M&P M2.0, which have now switched it to. Elevation and windage adjustments are precise.
