The Leupold 59035 is a uniquely designed cover for Leupold scopes crafted post-2003. This Alumina Flip-Back lens cover utilizes robust neodymium magnets to maintain a secure closure, coupled with triple O-ring seals to ensure optimal safeguarding from external elements. Its striking feature lies in its silent and smooth opening mechanism, where the cover folds flat against the scope when open.Meticulously constructed from the durable 6061-T6 aircraft grade aluminum, these lens covers are intricately machined for quick and user-friendly operation. The low-profile stance when open sets these Flip-Back lens covers apart from the competition. Both round objective and ocular models are designed to rotate, permitting them to open in any desired direction.
