Butler Creek Flip-Open Eyepiece Cover Size 07 (1.46"/37mm) - Black Polymer 20070

Keep your scope's eyepiece protected when it matters most with the Butler Creek Flip-Open Eyepiece Cover Size 07. Sized for 1.46-inch (37mm) eyepieces, this black polymer cover seals out the elements until the moment you need to shoot. Unlike caps that require you to remove and pocket them, Butler Creek's flip-open design lets you swing it aside with a thumb, keeping your shot window open and your optics shielded in one fluid motion.

Built for hunters and shooters who work in harsh conditions, this eyepiece cover creates a watertight and airtight seal that protects against rain, snow, dust, and moisture. The spring-loaded hinge is silent—no mechanical clicks to spook game or break concentration on the line. The ambidextrous design works equally well whether you're right-eye or left-eye dominant, and it's tough enough to function reliably in temperatures down to –40°F, whether you're glassing high country in winter or running a predator rig at dawn.

The Size 07 fits standard 37mm scopes and is a must-have for rifle scopes, spotting scopes, and other optics that spend time outdoors. It's the kind of simple gear that prevents expensive damage and keeps you ready when opportunities are brief.
