The Butler Creek Flip-Open Scope Cover Size 34 Objective from Butler Creek delivers unmatched lens protection for hunters and shooters, combining a fast flip-open design with a whisper-quiet spring hinge to keep your eye on the target while conserving stealth in the field. Custom-fit to your scope, these covers create a watertight, airtight seal and secure with friction mounts that anchor firmly without adding bulk, ensuring reliable performance in harsh environments. An airtight semi-O-ring guards against dust and moisture, and the cover is tested to operate in extreme conditions down to -40F, making it a dependable choice for early morning dew, rain, or freezing temps. Truly ambidextrous, the lightweight design weighs less than an ounce, so youll hardly notice it on the optic as you transition between shots, stalks, and sits. Manufactured in black, the Size 34 covers are specifically made to fit your objective lens, providing durable protection when youre tracking game or waiting for the narrow window of opportunity to open up.
