When it comes to selecting the right torque for your Leupold scope ring, you need to consider several factors. First and foremost, you want to make sure that the torque is appropriate for the size of your scope and its mounting system. Generally speaking, a good rule of thumb is that a 1-inch tube requires about 4 inch-pounds (in-lbs) of torque when using steel or aluminum rings; 6 in-lbs when using composite polymer or titanium rings; and 8 in-lbs if you’re dealing with heavy duty steel rings. For larger scopes with 30mm diameter tubes, 7 in-lbs should be used with steel/aluminum while 10 in lbs may be necessary for heavier materials. No matter what type of material you use, however, always double check manufacturer's instructions as recommended torques can vary greatly depending on an individual product's design features.
