Butler Creek 30300 Flip-Open Objective Scope Cover 49.80mm Size 30 Black Polymer

The Butler Creek 30300 Flip-Open Objective Scope Cover is a slip-on protective cap custom-fit to rifle scopes with a 49.80mm objective bell (Butler Creek Size 30). It shields the front lens from dust, moisture, and impact while creating a watertight and airtight seal around the scope's objective housing.

Molded from durable black polymer, the cover uses a fast flip-open design with a silent hinge so you can keep your eye on the target without spooking game. The spring-assisted lid flips open at the touch of a finger and snaps closed to protect the optic between shots or while carrying the rifle through the field.

Rather than a one-size universal fit, Butler Creek Flip-Open covers are sized to match the scope's own objective bell measurement for a precise, rattle-free fit, and weigh less than an ounce. Tested to -40 degrees, the 30300 is built to perform in harsh hunting and shooting conditions and installs in seconds by slipping directly over the objective housing.
