I recently upgraded a scope on a CZ 452, but I haven't yet tightened the screws on the top half of the rings (these are the screws that keep the rings together around the scope, not the screws that attach the scope to the rifle) because I haven't gotten the scope level yet. I am planning to do that this evening. The scope rings are Millett Angle-Loc rings made of aluminum. I haven't been able to find a torque value for these screws on these rings. I've seen general guidance that suggests everything from 15 in-lbs. to 25 in-lbs. Should I just go with 15 in-lbs. and call it a day?
