Butler Creek 30130 Flip-Open Objective Scope Cover 38.90mm Size 13

The Butler Creek 30130 Flip-Open Objective Scope Cover delivers instant lens protection with one-handed operation for riflescopes with 38.90mm objective lenses. This polymer cover system eliminates the fumbling and delays associated with traditional lens caps while maintaining crystal-clear optics in harsh conditions.

What Makes This Different

Unlike standard screw-on caps that get lost or require two hands to remove, this flip-open design stays attached to the scope while providing immediate access to the objective lens. The spring-loaded mechanism opens with a simple thumb press and automatically locks in the open position. Butler Creek's precision sizing ensures a secure fit without binding or slipping on Size 13 objective bells.

Key Features

• One-handed flip-open operation with spring-loaded locking mechanism
• Precision-fit for 38.90mm objective lenses (Size 13 designation)
• Durable black polymer construction resists impact and UV degradation
• Stays attached to scope - eliminates lost caps in the field
• Clear opening provides full light transmission when deployed
• Low-profile design won't snag on vegetation or gear
• Compatible with most riflescopes featuring 38.90mm objective diameter

Field performance centers on reliability and speed. The cover protects expensive optics from rain, snow, dust, and debris during transport and storage, then deploys instantly when targets appear. Hunters appreciate the silent operation that won't spook game, while tactical users rely on the quick deployment under stress. The polymer material maintains flexibility in temperature extremes from -20°F to 160°F.
