Meprolight mpo-f optic sight - Meprolight MPO-DF Open Emitter Pistol Sight with RMR Footprint 3.5 MOA Dot

I purchased two of these MPO-F red dot sights from Optics Planet. They are an underrated sight for the price point in my opinion. RMR foot print, clear glass with easy to find 3.5 MOA dot, which I have struggled with moving to dot sights on pistols over the past few years. One button to control all features and on / off, keeping it simple.
The only con in my opinion of this sight is the battery tray is not secured to the side of the housing with a set screw or screw on cover. It just seats in the side of the optic. Could be a draw back for extreme use shooters. Note, I’ve had zero issues with this.
Solid 4.5 out of for 5
Thanks Optics Planet !
Great prices, happy customer
