I would recommend this item to a friend.

Hard to beat

For the price, I know of nothing close to this scope. I use it on a springer, and after manually adjusting the objective lens (front) for parallax, it does everything I need a scope to do, and holds up well to the recoil. A quality set of rings, or one piece mount is recommended for the best results. Nice scope.
Surprising quality for the price
If you're shooting at different ranges frequently, you ought to consider a scope with an AO option for convenience

First of all it's rubber armored, not anodized as depicted. The lens coating makes everything blue. The reticle is not the P4 sniper, just a standard crosshair. Had to peel the rubber off of it to put different rings on it. The ones that come on it are for a weaver or picatinny base and are too big for the integral base on air guns. Glad it was "inexpensive".
