Butler Creek 30340 Flip-Open Objective Scope Cover 53.30mm Size 34

The Butler Creek 30340 Flip-Open Objective Scope Cover provides instant lens protection with quick one-handed operation for 53.30mm objective scopes. This polymer cover eliminates the fumbling and potential loss associated with traditional threaded caps while maintaining a weatherproof seal.

What Makes This Different

Unlike static lens caps that require removal and storage, this flip-open design stays attached to the scope at all times. The spring-loaded hinge mechanism allows shooters to flip the cover open with a simple thumb press, even while wearing gloves. The precision-molded polymer construction resists impact damage that would crack traditional lens caps, while the integrated tether system prevents accidental loss during field use.
