Better than i expected - Steiner MPS Micro Red Dot Sight- 3.3 MOA Dot Fully Enclosed with 1x Magnification, Waterproof and Shockproof, ACRO Footprint, Heritage Warranty

I wasn't expecting much from an enclosed optic but this one has surprised the h$ll out of me. I hear the battery life isn't great but I'm not using this for edc. I purchased it to go on a glock 49 mos7. I didn't realize an mos7 was a factory acro cut glock. The gun is being used for USPSA and gets the job done. The glass is clear. The dot gets more than bright enough and doesn't present a ghost dot or glare when shooting towards the sun.
