The Butler Creek Size 17 flip-open eyepiece cover is a fast-action lens protector designed for hunters and shooters who need reliable optics protection without slowing down when game appears. This 1.67"/42.50mm cover fits scopes with that specific objective diameter and combines a friction-mount design with spring-hinged flaps that open silently—critical when every second and every sound matters in the field. Built from durable black polymer, it's engineered to seal out the elements while staying light enough that you'll barely notice it on your rig.
Speed and silence are the hallmarks of this eyepiece cover. The thumb-actuated flip-open design lets you expose your glass in a single motion without fumbling or delay, while the quiet spring hinges won't alert nearby game to your movement. The semi-O-ring seal creates an air-tight and water-tight barrier around your objective lens—keeping dust, moisture, and mud out during wet weather or dusty conditions. It's tested to function reliably at extreme cold, down to -40°F, so you can hunt confidently from early season through late-season conditions.
Installation is straightforward: the water-tight custom-fit friction mounts grip your scope barrel securely without tools or permanent modification. The cover is truly ambidextrous, so lefties and righties alike can operate it naturally. At less than an ounce, it adds virtually no weight to your optic, making it ideal for hunters who count every gram on a backcountry hunt. Butler Creek also makes Size 17 covers for spotting scopes, so you can match protection across your glass.
