LOL I think a half dozen different manufacturers sell that VERY SAME SIGHT. Somebody must make the dang things and everybody stamps their names on them. The one I bought was from Academy and was a BSA brand. About $60. It is mounted on my U22 right now. Works fine for a cheap sight.
However, I like this one better:
I got it at Academy also. It is smaller than the average big ugly red dot unit and has an itty-bitty dot. Very precise. Also the brightness goes to 11 and is bright enough for super-sunny days. Something I can NOT say for the reflex sight.
