[QUOTE="Magnumdude, post: 383788, member: 751"] From your description, you tightened the ring screws what John Barsness calls, "Farmer tight." That is indeed too tight, and could even crush your scope tube in severe cases. Using an allen wrench, insert the long end into the screw, and using your thumb and index finger only, grip the small end of the wrench and tighten the ring screw. That will result in approximately 15 to 20 inch/pounds of torque. That's a safe torque. Another issue could be the rear ring is mounted too close to the power adjustment ring. In some cases I've seen this cause the power ring to bind. I'm not sure what you could do about that. [/QUOTE]
