You should be fine Cheers Jay 3/8 inch and 11 millimeters are not the same. 3/8 inch = .375 and 11mm =.433 or about .058 thousandths difference. Some, but not all scope rings are compatible to both size dovetail rails. The ring clamp can be rotated to fit either or. BKL scope rings have enough tolerance to clamp onto either, but use a bolt to force them open enough to fit 11mm. Though mine fit 11mm without needing to be spread open, never used 'em on a 3/8 rail.
Since there is a difference of .058, mixing mounts and dovetails (3/8 and 11mm) will result in a .029 off the center of the bore mounting of the scope. Not a very big error! john
Thank you all for the info. You guys are light years ahead of me in the technical knowledge dept. I checked further and found out that the company not only makes the 3/8, but also has a model called Magnum which reportedly fits both the 11mm and 3/8.
