Butler Creek 30210 Flip-Open Objective Scope Cover 44.10mm Size 21

The Butler Creek 30210 Flip-Open Objective Scope Cover provides instant lens protection with quick deployment for 44.10mm objective lenses. This polymer scope cover eliminates the fumbling with traditional lens caps during critical moments while maintaining complete optical clarity when opened.

What Makes This Different

Unlike removable lens caps that can be dropped or lost, this flip-open design stays permanently attached to the scope. The spring-loaded mechanism opens with finger pressure and locks securely in both open and closed positions. The low-profile design adds minimal bulk while providing complete protection from debris, moisture, and impact damage.

Key Features

• Fits 44.10mm objective lens diameter with secure friction mount
• Spring-loaded flip mechanism operates silently in field conditions
• Black polymer construction resists UV degradation and temperature extremes
• Stays attached to scope - eliminates lost cap problems
• Locks open and closed with positive retention
• Ultra-low profile adds less than 0.5 inches to scope length
• Compatible with most variable and fixed power riflescopes

Field performance remains consistent across temperature ranges from -20°F to 150°F without binding or failure. The cover opens instantly under pressure, making it suitable for hunting situations where speed matters. Competition shooters appreciate the ability to protect optics during transport while maintaining rapid deployment capability.
