Butler Creek Flip-Open Scope Cover, Size 20, Eye Piece

A Butler Creek Flip-Open Scope Cover, Size 20, Eye Piece is a quick-access lens protector designed for hunters and shooters who need reliable optics protection without fumbling when the moment counts. This eyepiece cover combines a fast flip-open design with a custom fit to your scope, so you can keep your eye downrange and react instantly when an opportunity appears.

The cover uses friction mounts that anchor securely to your scope tube, and a semi-O-ring seal that keeps dust and moisture out when closed. The hinge mechanism operates silently—a real advantage in the field when even small sounds can spook game. Its ambidextrous design works equally well whether you shoot right or left handed, and at less than an ounce, it adds virtually no weight or bulk to your rig.

Butler Creek engineered this Size 20 eyepiece cover to handle harsh field conditions, including temperatures down to –40°F. The watertight, airtight design means your scope's lens stays clean and dry whether you're glassing in rain, hunting in snow, or sitting in a blind for hours. When you're ready to shoot, a simple thumb flick opens the cover and gets it out of your line of sight in a split second.
