Butler Creek Flip-Open Objective Scope Cover, 1.646 in / 41.8mm

Hunters and precision shooters who want their glass protected without adding bulk turn to the Butler Creek Flip-Open Objective Scope Cover (brand part no. 30190), sized here at 1.646 in / 41.8mm to fit the objective lens of a specific scope. The custom-fit friction mount creates a water-tight, air-tight seal that keeps rain, dust, and grit off the glass, while silent spring hinges let the cover flip open with a touch of the thumb the instant you need to shoulder the rifle. Butler Creek offers this cover in more than 30 sizes, so matching it to your exact scope diameter gives a snug fit a generic cover can’t. It weighs next to nothing and mounts once, then stays out of the way until you need it.

Key Specifications

• 1.646 in / 41.8mm objective lens size is custom-fit to match this specific scope diameter rather than a loose universal fit.
• Water-tight, air-tight friction-mount seal keeps rain, dust, and grit off the glass between shots.
• Silent spring-hinge flip-open design opens with a touch of the thumb without a loud snap that can spook game.
• Cold-weather tested to -40°F so the hinge and seal keep working in harsh hunting conditions.
• Truly ambidextrous mounting works the same whether the rifle is shouldered left- or right-handed.
• Weighs less than an ounce so it adds negligible bulk to the end of your scope.
• 4.90 in reference length reflects the sizing used for this specific cover.
• Manufacturer size #19 is the catalog size designation for this specific cover.
• Reusable, remountable design attaches and removes repeatedly without wearing out or losing its seal.
