The Butler Creek 21314 Multi-Flex Flip-Open Eyepiece Scope Cover delivers reliable protection for your optic’s eyepiece with a simple, proven design. Built from durable polymer and sized for 39.90–40.80 mm ocular bells (Size 13/14), it forms a tight, weather-resistant seal that keeps dust, moisture, and debris off your glass while remaining lightweight and easy to use.

This slip-on cover uses Butler Creek’s Multi-Flex collar to accommodate a wider range of scope eyepiece diameters, making it a practical choice for hunters and shooters running different optics. The flip-open lid is operated by an ergonomic, non-slip button and a silent hinge, so you can bring the scope into action quickly without drawing attention. Tested to perform in harsh temperatures down to -40°F, it’s well suited for field use, range sessions, and general hunting setups where dependable lens protection matters. The design reflects Butler Creek’s long-standing reputation for functional, purpose-built scope accessories.
