The Butler Creek 30020 Flip-Open Objective Scope Cover 31mm Size 02 Black Polymer is built to keep your optic’s objective lens clean, dry, and ready when it matters. Custom fit to 31mm objectives, it forms a watertight, airtight seal and pops open instantly with a light touch of your thumb, so you can take the shot during brief openings in heavy weather or low-light conditions.

This compact cover weighs less than an ounce yet shrugs off hard use and cold down to -40 degrees Fahrenheit. Its slip-on design makes installation straightforward, while the silent flip-open hinge helps you stay focused on the target without spooking game. Ideal for hunting, range work, and general field use, it reflects Butler Creek’s long-standing reputation for practical, reliable optic protection.
