I bought a Crossman break action (1 pump) pellet gun. The gun seems to be of decent quality, but it came with a CenterPoint 4X scope which I found to be useless. I wasted about 150 pellets to find that I can't get better than 3 inch groups at 15 yards. Out of frustration i called CenterPoint and they offered to send me a new scope. I decided that it's not worth taking the chance of getting another POS scope from them. I read reviews that told the same story as mine, scope could not hold a zero and was all over the place. So I'm looking for recommendations on a decent scope for a 177 air gun.
