Butler Creek 02A Objective Flip Open Scope Cover – Black, 30mm (1.181")

Premium protection for your optics in the field

The Butler Creek 02A Objective Flip Open Cover in a sleek black finish is a lightweight, weather-ready shield for your ocular lens. Designed for a 30 mm (1.181 inch) ocular, it stays out of the way when you need to focus, yet springs to life at a moment’s notice to protect your lens between shots.

Crafted for hunters and shooters who demand reliability, this cover features a watertight friction mount and a Semi O-ring that anchors the cap securely, helping seal out dust and moisture. The ocular cover itself includes a large push button for quick, spring-loaded opening, so you can protect your optics and respond to changing moments with minimal interruption.

What makes it stand out is the balance between protection and speed. The flip-open design, combined with a truly ambidextrous silent spring hinge, keeps game undisturbed and your eye on the target. At well under an ounce, it won’t add noticeable weight to your setup, and it has been tested to operate in extreme conditions down to -40 degrees. This is not a gimmick—it's a practical accessory built to endure demanding environments.
