The Butler Creek Flip-Open Scope Cover Size 19 Eyepiece delivers premium lens protection for hunters and shooters, with a black, ultralight design that weighs less than an ounce and is truly ambidextrous. Custom-fit to your scope, this cover forms a watertight, airtight seal and opens with a simple thumbs action, ensuring you can take your shot through the narrow window of opportunity even in extreme conditions. Its fast flip-open design keeps your eye on the target, while silent spring hinges prevent spooking game. A water-tight friction mount anchors the cover securely, and an air-tight semi-O-ring keeps dust and moisture out, preserving clarity and reliability in the field. Tested to -40F, it performs reliably in harsh environments and is also made for spotting scopes, offering versatile protection across optics setups. Crafted by Butler Creek in the Philippines, this accessory combines rugged durability with practical functionality, enabling quick access and dependable protection when every moment counts.
