The Butler Creek Flip-Open Objective Lens Cover in Size 21 (44.10mm) is a rugged, purpose-built lens protector designed for hunters and shooters who demand gear that keeps up with unpredictable field conditions. This black polymer cover mounts directly to your scope and opens instantly with a thumb flick, so you're never fumbling with caps when the moment to shoot arrives. Whether you're glassing in fog, rain, or snow, it seals tight to shield your objective lens from the elements without slowing you down.
Built with a semi-O-ring design, the cover creates an air-tight, water-tight barrier that keeps dust and moisture away from your optics—critical when you're hunting in extreme weather or storing gear between seasons. The friction-fit mounting system holds the cover securely in place without tools, and the silent spring hinges won't produce the noise that spooks game at close range. At less than an ounce, it adds virtually no weight to your setup, and it's rated to perform reliably in temperatures down to –40°F.
The truly ambidextrous design works equally well for left- and right-handed shooters, and the flip-open mechanism lets you keep your eye on target and your hands on the gun. Size 21 fits 44.10mm objective lenses—verify your scope's objective diameter before ordering to ensure a proper custom fit. For serious hunters and precision shooters who won't leave their glass unprotected, this is straightforward, no-nonsense lens cover engineering.
