I was a little doubtful of the accuracy of this optic when outfitted to my son's 22LR. I put the optic on the included 1913 rail that came with the Ruger 10/22 and started shooting. With minimal effort, the optic was zeroed at 25 yards within 5 minutes and after that, it was plinking time. Quick acquisition time and resembled a lot of the red dot optics. Clarity can be adjusted by using a dimmer setting as there are many on this. Haven't drop tested this optic but I don't do that to any of my guns. This optic was a great value and far exceeded my expectations for such a cheap optic. I am planning to buy a few more and try them on other caliber rifles.
