I'm only a couple of weeks into owning my Mark II Target. It had a BSA on a Weaver mount when I bought it. I bought the Barska Reflex and put it on. After returning today from a range trip I noticed that the Barska was a little loose. I removed the Barska and found that the rear screw is stripped. The front screw is OK. I guess the gunsmith at the range could fix it somehow but is there anything that I could do to save the cost of the gunsmith. Can I just use some Locktite on it and let it dry and be OK?
