Butler Creek Flip-Open Objective Lens Cover, Black Polymer, 62.50mm, Size 47 (Model 30470)

The Butler Creek Flip-Open Objective Lens Cover in Size 47 is a practical and reliable solution for keeping your scope's front lens clean and protected in the field. Designed to fit scopes with a 62.50mm objective, this black polymer cover uses a custom-fit friction mount that locks securely to your scope without requiring tools or modification. Whether you're glassing from a stand, working through brush, or sitting in variable weather, this cover stands ready to shield your optics from dust, moisture, and the elements until the moment you need to take your shot.

The appeal of a flip-open design is simple: you get immediate lens access without removing anything. Spring-loaded hinges open with thumb pressure and stay silent—a small but real advantage when game is close. The semi-O-ring seal is designed to keep moisture and dust out while the cover sits closed, helping maintain clear glass when conditions turn wet or dusty. Butler Creek tested this cover down to –40°F, so cold-weather hunters and shooters can count on it performing when it counts.

At less than an ounce, the Size 47 cover adds negligible weight to your setup. The ambidextrous flip mechanism works equally well whether you're right- or left-handed, and the friction-mount design means no permanent installation—use it on one scope or swap it among compatible optics. If you run multiple rifles or frequently relocate your scope, that flexibility is worth having.

Frequently Asked Questions

Will this Size 47 cover fit my scope?

The Size 47 is designed for scopes with a 62.50mm objective lens. Butler Creek publishes a size chart to help match covers to optics—verify your scope's objective diameter before ordering to ensure proper fit.

How does the friction mount work?

The cover uses a custom-fit friction mount that grips your scope's objective bell. No tools, adhesive, or modification is required—it seats snugly and stays in place through normal hunting and shooting use. You can remove it and reposition it anytime.

Is the flip mechanism truly silent?

Yes. The spring hinges are designed to operate quietly, which is important in hunting situations where noise can spook game. The open and close action is smooth and controlled.

Will this cover work in wet conditions?

The semi-O-ring seal and friction fit are designed to create an air-tight, water-tight barrier when the cover is closed, protecting your lens from moisture, dust, and spray. The polymer is tested and rated for use down to –40°F.
