Get a gun vice and a brass leveling kit and a torque driver. Do it right. If your rings are going on a rail push them to the forward end of whichever slots youll be using. If youre mounting rings directly to your rifle a little squirt of some brake clean type shit into them itty bitty screw holes, while holding a paper towel on the inside, will clean the threads up so the loctite will work right. Tighten shit evenly and to spec. Keep the rings off the bell. Im sure theres a million videos online.
