I doubt that it's the scope as Element scopes are pretty rugged. Something is loose. Check that all screws are tight. Stock, rail, etc. Verify that your rings are properly torqued down. Check the manual for both rings and scope as they're probably different. Most likely 15 ft/lbs or more. But, don't over tighten as that could strip the threads or, worse, crush the scope's main tube! If you don't have a torque wrench - beg, borrow, or buy one!
