Quick Answer
Loose scope mounts can be frustrating and detrimental to accuracy during a hunt. To troubleshoot this issue, inspect the scope's mounting screws for any signs of overtightening, which can damage the threads. Ensure the scope is properly aligned and tightened in a star pattern.
Inspecting the Scope Mounts
When inspecting the scope mounts, look for any signs of overtightening, such as damaged threads or stripped screws. To avoid damaging the threads, apply a thin layer of threadlocker to the screws before tightening them. A good rule of thumb is to tighten the screws in a star pattern (tightening one screw a little, then moving to the next one, and so on) to ensure even pressure.
Tightening the Screws
When tightening the screws, use a torque wrench to apply the recommended amount of torque (typically 10-15 in-lbs). If the scope is still loose after tightening the screws, it may be necessary to adjust the scope’s position on the rifle’s receiver. Use a bubble level to ensure the scope is properly aligned, and tighten the screws again in a star pattern.
Verifying the Scope’s Alignment
To verify the scope’s alignment, use a boresighter or a laser bore sighter to ensure the scope is properly zeroed. If the scope is still loose after verifying its alignment, it may be necessary to replace the scope mounts or consult a professional gunsmith.
