Leupold 59045 Alumina Flip Back 40mm Lens Cover

The Alumina® Flip-Back™ lens covers feature powerful neodymium magnets to hold them securely closed, and triple O-ring seals to provide maximum protection from the elements. Constructed out of durable 6061-T6 aircraft grade aluminum, they are precisely machined to allow for quick and easy operation, and a low-profile position, when open, make these Flip-Back lens covers stand above the rest. The round objective and ocular models can rotate so that they can open in any direction.
