Quick Answer
Optimal torque settings for shotgun scope mounts typically range from 20-40 inch-pounds, depending on the mount type and manufacturer's recommendations. This range helps ensure a secure and durable attachment without overtightening the mount. Torque settings above 40 inch-pounds can risk damaging the mount's threads or scope base.
Choosing the Right Mount
When selecting a shotgun scope mount, consider the type of shotgun, scope weight, and intended use. For most shotguns, a Picatinny rail mount is a good choice, which allows for easy scope adjustment and attachment. However, for older or collectible shotguns, a traditional dovetail mount may be more suitable.
Mount Torque and Scope Attachment
When attaching the scope to the mount, use a torque wrench to ensure the recommended torque setting is met. For most Picatinny rail mounts, start with 15-20 inch-pounds and increase in 5-inch-pound increments until the recommended torque is reached. Be careful not to overtighten the mount, as this can damage the scope base or mount threads.
Considerations for Scope Mount Torque
Scope mount torque also depends on the scope weight. Heavier scopes require more torque to secure them properly. For scopes weighing over 12 ounces, increase the recommended torque setting by 5-10 inch-pounds. Additionally, consider the type of scope and its attachment method. Some scopes, such as those with a large objective lens, may require additional torque to prevent lens shift or damage to the scope body.
