Just received my new HS .223. It has factory fitted 2 piece cross slot bases. I assumed a set of Leupold QRW's would fit - and they do sort of, but no where near as well as they could. The HS bases are slightly wider than the QRW's so that the rings when tightened are cocked up slightly on the lever side, and the clamp has minimal purchase on the base. What rings should I have bought?

Cheers and thanks for any info you can give.
