Butler Creek Flip-Open Objective Lens Cover - 1.612" (40.9mm)

The Butler Creek Flip-Open Objective Lens Cover in 1.612" (40.9mm) is a purpose-built protective accessory designed for hunters and shooters who need fast, reliable lens access when the moment matters. Custom-fitted to your scope, this flip-open cover combines rugged protection with speed—no fumbling with caps when game is in your sights or the range is hot. The semi-O-ring design seals out dust and moisture, keeping your optics clean and clear in unpredictable field conditions, while the lightweight construction keeps your rifle balanced and ready.

What sets this cover apart is its thought-out engineering. Silent spring hinges flip open instantly without spooking game, and the friction-mount design locks securely to your scope without tools or permanent installation. Whether you're glassing at dawn, waiting out a downpour, or shooting in extreme cold, this accessory keeps your objective lens protected until the second you need to glass or shoot. Tested to –40°F and weighing less than an ounce, it's tough enough for the harshest seasons without adding bulk to your setup.

The 1.612" (40.9mm) size is custom-fit for specific scope models, so you get a watertight, airtight seal rather than a generic one-size-fits-most cover. The ambidextrous flip design works from either side, and the spring hinges are engineered to stay silent—a critical detail for hunters where quiet gear keeps your edge. If you're serious about protecting a quality scope investment while keeping it ready to shoot, this is the cover that delivers.
