Bad mounts - Barska 1x30mm Red/Green Dot Sight

This sight is good but the mount provided is junk. The one I got from Optics Planet had several of the ring to scope screws loose. The picatinny mount screws are pure garbage. They stripped out with hardly any tightening. Ordered some Vortex from Amazon. Hoping I can make them work. So, buyer beware. Like I said. The sight is nice. The battery they tell you to get is not what they provide in the box. The o-ring around the battery compartment doesn't want to stay in place. Spend a little more and get something from Vortex.
