Butler Creek 30010 Flip-Open Objective Lens Cover, Black Polymer, 25.40mm Size 01

The Butler Creek 30010 flip-open objective lens cover is a purpose-built protection solution designed for hunters and shooters who demand quick access to their optics without sacrificing weatherproofing. This Size 01 model fits 25.40mm objective lenses and combines a spring-hinged flip design with a secure friction-mount system that keeps the cover attached to your scope body while allowing one-handed removal. Whether you're glassing across a ridge or holding position in unpredictable weather, a quality objective lens cover prevents water, dust, and condensation from fouling your glass — and the Butler Creek approach does it without fuss or noise.

Built from durable black polymer, this cover weighs less than an ounce and won't add noticeable bulk to your rig. The air-tight semi-O-ring seal blocks out the elements, and the custom-fit design is engineered to stay put through rough handling and field conditions. Silent hinges mean your cover won't betray your position with a telltale snap or click, a detail that matters in draw-down moments. The truly ambidextrous flip mechanism works equally well for left- and right-handed shooters, and the simple push-to-open action gets your scope picture clear in the time it takes to acquire a target.

If you're running optics in the field — whether for hunting, tactical shooting, long-range practice, or any situation where your scope matters — thermal cycling and moisture ingress are real threats. This is why scope caps aren't optional gear; they're insurance against a blurred shot when it counts. Butler Creek has tested the 30010 down to –40°F, so it performs in the conditions where you might actually hunt.
