Yall seem to be forgetting a crucial step in scope mounting. I cannot remember how many scopes I've seen with "ring marks". These are caused by3 things-ring misalignment and/or neglecting to lap steel rings in(exception being burris sig rings with plastic inserts),or overtightening. If you go to a basspro or d**ks,they won't do the same job that a gunsmith or knowledgeable tinkerer will. You're spending a lot of money to waste by damaging scope by improper mounting. You CAN buy scope lapping equipment at midway.brownells and other places. All it takes is a 1" steel bar with handle welded on and lapping compound to lap scope rings and a simple double pointer to assure the rings are aligned perfectly. Remember-ring marks are not only uneccesary-they are also indication of scope damage.
