Great mini sight - OpticsPlanet Exclusive 1 x50 mm Red Dot Mini Reflex Sight, 5 MOA Dot Reticle

Great little reflex sight. I mounted it on a Beretta Neos 22 cal and it fits and works perfectly. Put about 600 rounds through my Beretta and it holds the red dot on target. There is no drifting from the set point. Not sure how it would hold set point on a high caliber gun but it works great on the low caliber handgun.
