Ncstar, This is a good little scope for the price, but it has some drawbacks. The focus isn’t as good as it should be, and the scope doesn’t come with rings for mounting on your rifle or crossbow. Still, for the price, you get a reasonable scope for shooting out as far as 100-150 yards or crossbow hunting at any range NcStar. It’s a great product for what you are paying for.
