The Butler Creek Element Flip Open Objective 50mm (BCESC50) is a rugged, multi-fit rifle scope cover designed to protect optical glass from dust, rain, mud, and impact in harsh outdoor environments. Engineered with a flexible, stretch-fit rubber sleeve and stainless steel hinge pins, the cap provides an airtight and watertight seal over rifle scope objective bells measuring between 45 mm and 50 mm (1.73 in to 1.97 in) in outer diameter. Its modular design includes interchangeable disk inserts and a dual-position folding lid that secures clear of the shooter's line of sight.

Key Features

• Multi-Flex Rubber Sleeve: Stretches across a 5 mm external diameter span to securely fit objective bells from 45 mm to 50 mm, preventing moisture and grit ingress without requiring exact millimeter-sized caps.
• Dual-Position Hinge: Flips open to both 180° and 270° angles using stainless steel hardware, resting nearly flat against the scope tube to maintain full situational awareness and field of view.
• Modular Interchangeable Disks: Includes three quick-swap lid inserts: a solid black disk for light and glint blocking, a clear lens disk for target acquisition in rain or snow with the cap closed, and a printable ballistic data disk for holding caliber-specific DOPE cards.
• Recoil-Resistant Build: Constructed from impact-resistant polymer and stainless steel pins to prevent accidental flip-open deployment under heavy magnum centerfire recoil.

Who is the Butler Creek Element Flip Open Objective 50mm for?

• Long-range precision shooters — Provides a dedicated ballistic data disk insert housed inside the flip-open rifle scope objective cover, allowing direct line-of-sight elevation and windage hold references that fold cleanly out of view at 180° or 270° angles.
• Hunters in dusty outback or alpine environments — Uses a stretchable rubber collar to form a sealed barrier over rifle scope objective bells with an outer diameter of 45 mm to 50 mm, preventing fine dirt, mud, and precipitation from reaching external lens coatings.

Less suitable for: Scopes with an objective bell outer diameter under 45 mm (1.73 in) or over 50 mm (1.97 in); optics outside this physical range require smaller or larger dedicated stretch-fit scope caps.
