Affordable & effective holographic - OpticsPlanet Exclusive Sightmark Ultra Shot A-Spec Reflex Sight 1x33 mm

I really like this red dot sight. It uses a larger battery format so you get up to 2000 hours of use. Brightness controls, you can change the reticle. The size is comparable to other holographic sights. The QD attach system makes it easy to move between guns. For what most of us do to shoot I think this thing is plenty durable. I don’t drop my gun a ton but yes I do drop it. I leave the sight on with load in & out of the bag without issue. I have shot it in the rain with no problem. Works for me.
