Butler Creek Flip-Open Objective Lens Cover - Size 29 (48.70mm) Black Polymer 30290

The Butler Creek Flip-Open Objective Lens Cover in Size 29 (48.70mm) is a purpose-built objective lens protector designed for hunters and shooters who demand reliability in unpredictable field conditions. This flip-open scope lens cover combines rapid-access design with dependable weather sealing, letting you keep glass protected until the moment you need a clear sight picture. The custom-fit friction mount anchors securely to your scope's objective bell, while the semi-O-ring seal works to exclude dust and moisture—a critical feature when you're glassing in rain, snow, or across extended hunting seasons.

Speed matters when opportunity is narrow. The flip-open mechanism lets you expose your lens with a thumb flick, no fumbling or separate storage required. Silent spring hinges ensure the motion won't alert game, and the design is truly ambidextrous so it works for left or right-handed shooters alike. Weighing less than an ounce, it adds negligible bulk to your rig, and testing down to –40°F confirms it'll perform in serious cold. The black polymer construction is built to handle the realities of field use without adding unwanted weight or complexity to your optic package.

Whether you're hunting in wet mountain country, running your scope through a season of variable weather, or simply wanting a low-profile way to keep your objective glass clean between range trips, this Butler Creek cover delivers the kind of fit and function that makes sense. It's the kind of simple, effective gear that experienced hunters keep on their scopes year after year.

Frequently Asked Questions

Will this objective lens cover fit my specific scope?

The Size 29 is custom-fit to 48.70mm objective bells. Measure your scope's objective diameter or consult your scope manual to confirm compatibility before ordering.

Can I use this cover while shooting, or do I have to remove it?

The flip-open design is meant to be opened before shooting so your objective lens is fully exposed for a clear sight picture. It's not designed to be shot through.

How does the flip-open mechanism stay secure in the field?

The friction mount anchors the cover securely to your scope's objective bell, and the spring hinges hold it closed when not in use. Once flipped open, the mechanism stays out of the way until you flip it closed again.

Is this cover waterproof?

The semi-O-ring seal is designed to keep out dust and moisture. While the cover itself helps protect your objective lens from rain and wet conditions, it's not submersible and should be treated as weather-resistant field gear, not a waterproof container.
