Adjustable scope rings are must have. - Sun Optics Adjustable Airgun Rings & Airgun Ring/Base Combos

I purchased the SM0037 high scope mounts. They are very tall, I think that a medium would have taken care of it for using a 60mm tube. They adjust easy and hold the scope solid. They seem to hold well, yet I'm using this on a Co2 air rifle and a night vision set up. A couple of caveats, the up and down adjustment requires a full turn of the base to keep the mounts both on the same side. This can over adjust, perhaps this is a way around this that I'm not aware of. Still a nice feature and beats using shims. The side to side works well and this can be fine adjusted. The biggest downside to these rings is the cheap fastners heads. They work, yet the allen key is a sloppy fit. Other than that I really like them.
