Buck mark sight - Browning Buck Mark Reflex Sight, 3 MOA Dot Reticle

This is a good entry level optic for someone testing out what they want in a red dot. It is pretty durable. I originally used this on my Mossberg 500 shooting slugs and it held zero just fine. I switched to a better red dot, now I will probably use it on my AR pistol project.
Only negative thing I found is sighting it can be tricky. The adjustment is allen key and there is no click when you make changes. You have to slowly turn and then shoot to see results. Kind of a pain , but it will hold zero once it's dialed in pretty well.
