Query: Imperfect - could have been a lot better

The tag on these mounts state that they're for "all Benjamin and Sheridan pistols and rifles", and yet they fit my Benjamin 22 pellet gun so loosely that they slide back and forth, not to mention tick side to side. If I tighten them any more, the screw will bend or break, and I'll be worse off; to make this work, I'll need to fashion some spacers to put between the barrel and the mounts, taking care to choose a material that won't expand or change shape.Also, I took them to Sportsman's Warehouse, the store with the biggest gun supply, and they didn't have any way of mounting rings on top of these mounts in order to attach my scope. I'm going to have to special order those too.Putting a scope on a Benjamin rifle has turned out to be a huge chore, and these mounts missed two opportunities to make it easier, by (1) not fitting the gun snugly, and (2) providing a less usual "receiver groove".
