I just ordered the Burris signature Z rings. The standard Burris signature rings wouldn't work on my receiver mount, which I believe is a standard weaver style with the "rail" the rings slides over. The Z rings do, and the woman assured me it comes with inserts.

I hope it works out! For those of you who suggested thesignature rings, does this sound right, the"Z" version of signature rings to fit my receiver mount?

Thanks for all the advice!
