Butler Creek Flip-Open Eyepiece Cover, Black Polymer, Size 16 (1.66"/42.20mm)

A quality scope cover should protect your glass without slowing you down when the moment matters. The Butler Creek Flip-Open Eyepiece Cover, Size 16, is built for hunters and shooters who need fast, silent access to their optics. This black polymer flip-open eyepiece cover fits scopes with a 1.66" (42.20mm) objective diameter and opens with a quick thumb flick—no fumbling, no noise, no missed opportunities. Unlike fixed caps, these covers stay tethered and ready, keeping dust and moisture off your lens while staying completely out of your way.

Butler Creek designed these covers with a friction-mount system that grips your scope tube securely without tools or permanent modifications. The semi-O-ring seal blocks moisture and dust in wet, muddy, or dusty field conditions, and the silent spring hinges won't create the slightest sound when you flip them open—a real advantage when game is close. The construction is tough enough to handle hard use and cold weather; these covers are rated to -40°F so they'll perform in whatever your hunting season throws at you.

Weighing less than an ounce, the Butler Creek cover adds no real burden to your rifle setup. The design is truly ambidextrous, so lefties and righties both get smooth, instinctive operation. Because the cover uses a friction fit rather than adhesive or tight mechanical clamps, installation and removal are straightforward—just slide it onto the objective bell and you're done. If you shoot a spotting scope as well, Butler Creek makes covers for those too.
