Anyone ever heard of it? I have an RWS model 48/52 pellet rifle, a RWS 'C' mount, and a Simmons ProAir 4-12x40AO scope. The problem is, I can't get it to work together. The mount itself is adjustable, but no matter what I do with it all, it can't produce a decent group past 15 yards. Anyone have experience with this?
