Butler Creek Flip-Open Objective Lens Cover, Black Polymer, 35.20mm, Size 05 - Model 30050

The Butler Creek Flip-Open Objective Lens Cover in Size 05 (35.20mm) is a purpose-built objective lens protector designed for hunters and shooters who demand reliability in the field. This black polymer cover pairs rapid-access design with a custom friction-mount fit, so you're ready to acquire your target the instant conditions demand it. Whether you're glassing from a blind, waiting for a clean shot opportunity, or working through unpredictable weather, a quality lens cover keeps your optics clear and protected when it matters most.

The flip-open mechanism is engineered for speed and silence—spring hinges operate without noise that might spook game, and the cover clears your sight picture in a thumb's motion. The semi-O-ring seal and watertight design block dust and moisture, holding their integrity even in extreme cold (tested to –40°F). Custom-fit friction mounts anchor the cover securely to your 35.20mm objective bell without tools or permanent modification, and the ambidextrous hinge works from either side of your rifle. At less than an ounce, it adds no measurable weight to your rig.

Butler Creek lens covers are a field-proven choice for serious hunters and precision shooters. The Size 05 fits a specific range of objective diameters, so verify the model against your scope before ordering—a correct fit ensures the watertight seal and friction-mount security that make this cover worth carrying.
