I like the the Diana Bulls eye ZR Mounts myself. I just bought my second one. Shot some really good groups with it with both my Diana 52 and the 54 with it on my guns. Have a couple of thousand rounds with it on one gun or another. I have in the past used BKL and Diana one piece mounts with good results. Sports Match makes some decent mounts as well
My winning combination: BKL 11mm/Weaver riser and Weaver tactical rings. It’s rock solid even with the hardest recoiling springers. Properly torqued screws are essential
Another vote for bullzeye, I’ve tried a lot and I don’t know if any others that work like this that actually work. ANY solid mount will eventually move on you and or destroy your scope.
