Great, enclosed optic for ar pistol builds - Holosun OPMOD AEMS 1x0.87x1.1in Reflex Red Dot Sight

4.5 stars.⭐️. Bought this when it was on a terrific sale at Optics Planet. Mostly have EOTechs on my ARs but wanted to try this out on a smaller 7.5” .300 BLK AR pistol build. Locks up tight in the top pic rail, but imho the retention screw could be better. It’s a torx head screw, but a much smaller torx head size that could be stripped if you over tighten it. It’s an enclosed optic and has additional flip up protective covers on both ends. I got the green MRS with the dot and circle of death, similar to an EOTech. The backup solar feature is a nice added bonus. Zeroing in the sight was easily done, and the elevation/windage adjustments were positive but not super firm. I’ve shot over 1,000 rounds with it on, and it hasn’t lost zero yet. Battery compartment is secure and has a rubber gasket to protect against water intrusion. One of the best features is Holosun’s shake awake feature that puts the optic in a sleep mode to save battery life, and turns right back on with the slightest movement. I’ve tested it more times than I care to admit, and it works every time. Great for any home defense set up. Beats the EOTechs I have that all have to be manually turned on. One less thing to worry about if you have to grab your home defense weapon in a pinch. Can’t speak to the durability since I haven’t beat it up yet in training, etc., so ymmv. Would definitely buy again.
