Butler Creek 30330 Flip-Open Objective Scope Cover 51.90mm Size 33

The Butler Creek 30330 Flip-Open Objective Scope Cover protects precision optics from debris, moisture, and impact damage while maintaining instant access when it matters most. This size 33 cover fits 51.90mm objective lenses with a secure spring-loaded design that stays open during shooting.

What Makes This Different

Unlike fixed caps that require removal and storage, this flip-open design stays attached to the scope at all times. The patented spring mechanism holds the cover firmly open during use, preventing interference with sight picture or target acquisition. Butler Creek's polymer construction resists cracking in extreme temperatures where metal alternatives might fail.

Field conditions demand equipment that performs without hesitation. This cover opens instantly with thumb pressure, maintaining shooting readiness during hunting situations or competitive events.
