    Verified Purchase

    Mounts up very solid on standard picatinny rails and the dot is brignt and clear outside, as well as the auto dimming works well inside. More than bright enough for night and dusk shooting as well.

    Great price from Overstock.com. Very helpful CS rep when placing order (had trouble applying discount to order). Product exactly as advertised and was sighted in in just a few shots.

    Great red dot. Can't beat the price also. Shipping was fast I had trouble with a coupon and the Overstock staff was great. It has been years since I have purchased items from Overstock, but I'm going to start keeping them in my searches.

    Not trijijicon quality, but all right. Good mount. Protective cover has blemish in plastic that blurs the sight.
