I'll second the recomendation for Burris Signature Zee rings. They are a good set up with the delrin adapters and you won't need to lapp or epoxy bed the rings to get everything trued up. You can get offset inserts for the rings that will let you position the scope better for longer range or to better line it up with the bore. They do have small screws which you want to be careful with not to strip. If you don't have a torque screwdriver, just use the short end of the allen key with your thumb and finger...this should snug everything up pretty close to what the torque specs would be (15 in/lbs).
