The Butler Creek Flip-Open Objective Scope Cover Size 13 is purpose-built to shield your optic’s objective lens from dust, moisture, and impact while staying out of the way when it’s time to take the shot. Custom fit for 38.90mm objective diameters, this lightweight polymer cover forms a secure, friction-mounted seal that keeps your glass protected in demanding field conditions.

Designed for hunters and shooters who need fast access to a clear sight picture, the Flip-Open cover uses push tabs and a silent spring hinge so it opens instantly with a thumb press and stays out of your line of sight. Weatherproof construction, an airtight O-ring, and testing down to -40°F make it a dependable choice for everything from range practice to serious hunting trips, backed by Butler Creek’s long-standing reputation for practical, durable optic accessories.
