When tightening the ring screws down in one the scope has a tendency to rotate to the right due to the design of the rings, no big problem just have it lean to the left a certain amount before tightening and after a few trials and errors you usually find the right amount in short order. I've got three Aero mounts so I've done this before. Okay, so far so good but just had one do something I've not seen before, mounted a scope in one three days ago and I will swear I had it mounted perfectly vertical in the mount but I pick up the rifle this morning and the scope is canted to the right. Now before you guess that maybe the reticle moved you could also see it clearly moved by looking at the caps and it was in there tight. Anyone see a scope creep after the fact like this before in a Aero mount?
