(5 out of 5) Incredible Firearm
by Mark from River Ridge, Louisiana on November 29, 2017

Right out of the box this gun was sighted in. A friend and I took turns shooting from 25 feet away and we couldn't miss the bulls eye. By far the best gun I have fired right out of the box. The red dot was right on the money. Absolutely no failures to fire either. I highly recommend this gun. You won't be disappointed!
