Was installing some lightweight Talley one piece mounts tonight. I am on to tightening the last screw. The screw wasn't even tight yet, and next thing you know it, it twists off. Seems kind of odd really. Now I have a stuck screw in my gun. It sticks up between 1/8-1/4 inch. I tried to get it twisted out with a vice grips vertically but couldn't get it. I do have some blue lock tite on the threads also. One thing I thought about was creating a slot on top of the exhisting screw and trying to get it out with a screwdriver. Seems like a good way to mar everything up though. Probably best to just take it to a smith and see what they can do I am guessing. Anybody got any idea what a smith would generally charge to get it out of there for me. Thanks for any help ahead of time, I wasn't able to find the answers I was looking for while searching.
