Sorry this is not a barska scope, but i do have one on a 223 savage i like it for the money it ok, optics not bad, turrets seem ok returning back to zero, my barska is about three yrs old, the swat model 10x40x50, i think it is better than the tasco 10x40x50, but thats just my opinion.
The russian pso scope is completley different type of scope, when you adjust the the rectical it moves its position in the scope, seems weird after have all american type scope, i would not give up a leopold for it but it works well on a crossbow, mine anyways.
