The Butler Creek 30310 Flip-Open Objective Scope Cover Size 31 delivers simple, reliable protection for your optic’s 50.70mm objective lens. This lightweight polymer cover slips over the bell of your scope and forms a watertight, airtight seal, keeping dust, moisture, and debris off the glass while you move through changing conditions. A spring-loaded lid with a silent hinge flips open at the touch of your thumb so you stay focused on the shot instead of duty your gear.

This Butler Creek Flip-Open Objective Scope Cover is ideal for hunters and target shooters who need fast access to a clear sight picture without exposing their lens to the elements all day. Its ambidextrous operation, compact profile, and less-than-an-ounce weight make it a practical upgrade for field use, range sessions, and training with your favorite optic. Tested to -40°F, it reflects Butler Creek’s reputation for durable, purpose-built accessories that simply work.
