Spotted the Kwik Site 22 Adapter in the Natchez catalog. It looks like a Weaver Style Base, but it is designed to fit into the normal 22Rimfire Rifle Grooves. Once you have the 22 Adapter mounted, you can use regular Weaver Style Rings on your Grooved 22.

Has anyone tried one of them?

If so, how high is it?

I have tried them and they work fine, but I prefer the B-Square Weaver Adapters as they are a better solution for mounting a 1" scope using Weaver style rings on a 3/8" groove/dovetail. The only place that I've found the B-Square adapters is Brownells, while several retailers, including Cabela's, have the Kwik Site adapters.

Thanks for the info. I'll take a look at what B-Square has.
