Butler Creek 30310 Flip-Open Objective Scope Cover 50-70mm Black

The Butler Creek 30310 Flip-Open Objective Scope Cover provides instant lens protection with one-handed operation for scopes with 50-70mm objective lenses. This black polymer cover eliminates the fumbling and potential loss associated with traditional lens caps while maintaining quick target acquisition capabilities.

What Makes This Different

Unlike standard push-on caps that require two hands to remove and often get misplaced, this flip-open design stays permanently attached to the scope. The spring-loaded mechanism opens with a simple thumb press, allowing shooters to engage targets immediately without removing gear. The precision-molded polymer construction resists impact damage that would crack traditional lens caps.

Key Features

• One-handed flip-open operation for instant target engagement
• Fits objective lenses from 50mm to 70mm diameter
• Durable black polymer construction resists UV degradation
• Spring-loaded hinge mechanism rated for 10,000+ cycles
• Low-profile design prevents snagging on vegetation or gear
• Secure friction fit eliminates need for adhesives or tools
• Size 31 designation ensures proper fit for compatible scopes

Field performance remains consistent across temperature extremes from -20°F to 140°F, with the polymer material maintaining flexibility in cold conditions where rubber alternatives become brittle. The cover's slim profile adds minimal bulk to the scope system while providing complete protection from rain, snow, dust, and debris. Hunters appreciate the silent operation that won't spook game, while tactical users benefit from the rapid deployment capability.
