Surprisingly great micro dot for the money! - AT3 Tactical ARO Micro 3 MOA Red Dot Reflex Sight with Optional Riser Mount 1x23mm

Ive had this on my pistol for over a year. I've dragged it through all types of stuff and it has held up great. Most importantly its taken some tough hits and held zero. Has the same foot print as the Burris fast fire 3, and the Vortex Venom. The AT3 ARO is a lot cheaper and just as good in my opinion
