Butler Creek Flip-Open Objective Lens Cover - Black Polymer, 53.30mm, Size 34 (30340)

A quality scope cover is one of those small details that separates hunters who keep their glass in fighting condition from those who don't. The Butler Creek Flip-Open Objective Lens Cover in Size 34 is built specifically for your 53.30mm objective lens, offering the kind of custom-fit protection that keeps dust, moisture, and the elements off your optics when it matters most. The flip-open design means you're never fumbling with a cover that won't stay put or slows you down when the shot is on—just a quick thumb flip and you're ready.

What makes these covers worth carrying is their simplicity. The silent spring hinges won't make a sound when you snap them open (crucial when game is close), and the friction-mount system locks them securely to your scope body without any tools or complicated attachments. The semi-O-ring design seals out dust and moisture, protecting your lens in everything from wet mountain weather to ultra-cold conditions. Tested down to –40°F, they'll perform whether you're hunting high country in December or glassing from an overlanding camp in winter terrain.

Butler Creek engineered these for real-world use: they're truly ambidextrous, so it doesn't matter which hand you shoot with, and they weigh less than an ounce—not the kind of gear you'll notice in your pack but exactly the kind that keeps your optics clear when you need them. If protecting your scope investment is a priority, this is the kind of thoughtful accessory that pays off every season.

Frequently Asked Questions

Will this cover fit my scope?

The Butler Creek Size 34 is designed for objective lenses measuring 53.30mm in diameter. Refer to your scope's specifications to confirm your lens size matches 53.30mm before ordering. Butler Creek publishes a size chart to help you select the correct cover for your optic.

How does the mounting system work?

The cover uses a friction-mount design that anchors directly to your scope body without screws, clamps, or tools. It seats securely and stays put until you flip it open with a quick thumb motion.

Will the hinges make noise when I open it?

No. The spring hinges are designed to operate silently so they won't alert game animals when you flip the cover open during a hunt.

What protection does the seal provide?

The semi-O-ring seal creates an air-tight and water-tight barrier that keeps dust and moisture off your objective lens, helping protect your glass from the elements even in wet conditions or extreme cold down to –40°F.
