WOW These are awesome. I got some 30mm 2 piece for 11mm dovetail and I love them. I always wondered why they were so much more expensive than the non adjustable....but now that I have used them they are worth every penny. No more shimming. The scope is optically centered. Easy to adjust elevation and windage. Easy to align the scope over the center of the barrel even if the dove tail + lower mount stack up would have causedd the scope to be off center. Even small adjustments are possible with the jack screw system. The upper part of the mounts gimbal so the scope is not stressed like with shimming.
I have them mounted on a crosman 2400 custom shop gun converted to PCP with discovery internals so recoil will not be a problem, but they did come with two rear posts (one with a recoil stop pin, one without).
I the future I will be only buying b-square adjustable mounts. I am considering just replacing the mounts I have with new mounts. I like them that much.
They were $45 and worth it. I almost bought more $10 leapers mounts. I am really glad that I did not.
