The Butler Creek Element Flip Open Objective 55-60mm is a modular riflescope lens cover engineered to shield front optics from weather, dust, and debris while offering customisable data integration. Built with a high-strength polymer lid, a flexible multi-flex rubber sleeve, and stainless steel hinge hardware, this mechanical accessory secures over objective bells measuring between 55 mm and 60 mm (2.20 in to 2.36 in) in outer diameter. It features a push-button release with dual-position opening angles and comes with interchangeable modular disks, allowing shooters to switch between standard protection, transparent shooting, and direct ballistic data referencing.

Key Features

• Dual-Position Hinge: Spring-loaded push-button hinge opens to a 180-degree upright position or folds back 270 degrees flush against the scope body to prevent snagging and sight obstruction.
• Three Interchangeable Discs: Includes an opaque black disc for sun and glare protection, a clear lens disc for target acquisition in wet conditions without opening the cover, and a ballistic data disc for printable elevation and wind dope charts.
• Environmental Sealing: Flexible rubber stretch sleeve combined with an integrated O-ring profile creates an airtight and watertight friction-fit seal over the scope bell.
• Platform Agnostic: Purely mechanical, non-powered design that fits centre-fire, rimfire, and airgun optics within its specified diameter range.

Who is the Butler Creek Element Flip Open Objective 55-60mm for?

• Long-range precision shooters — integrates printable dope charts directly into the riflescope objective lens cover via a ballistic data disc, while mounting securely to optic housings with a 55 mm to 60 mm outer diameter.
• Wet-weather and variable-terrain hunters — utilizes an airtight rubber seal and an interchangeable clear lens disc that fits 55 mm to 60 mm scope bells, enabling target acquisition in rain or snow without opening the protective cover.

Less suitable for: Scope housings measuring strictly less than 55 mm or greater than 60 mm in outer bell diameter; these setups require a smaller-format (such as a 50–55 mm) or larger-format (such as a 60–65 mm) scope objective cover size variant to achieve a secure friction fit.
