Butler Creek 20100 Flip-Open Eyepiece Cover 1.51" Size 10 Black

The Butler Creek 20100 Flip-Open Eyepiece Scope Cover protects valuable optics from dust, moisture, and impact damage while maintaining instant target acquisition capability. This size 10 cover fits eyepieces measuring 1.51 inches (38.50mm) in diameter with a secure polymer construction that withstands field conditions.

What Makes This Different

Unlike static lens caps that require removal and storage, this flip-open design stays attached to the scope during shooting. The spring-loaded hinge mechanism opens with finger pressure and closes automatically when released. Butler Creek's polymer construction resists cracking in temperature extremes from -40°F to 140°F, outlasting rubber alternatives that become brittle or sticky over time.

Key Features

• Flip-open design eliminates lost lens caps during field use
• Fits 1.51-inch (38.50mm) diameter eyepieces precisely
• Black polymer construction resists UV degradation and chemical damage
• Spring-loaded hinge provides consistent opening tension
• Low-profile design clears scope rings and mounting systems
• Textured grip surface enables operation with gloves
• Compatible with most variable and fixed power riflescopes

Field performance centers on protection without compromising shooting speed. The cover opens silently for hunting applications and snaps shut to protect lenses during transport. Rain, snow, and debris stay off the eyepiece lens, preventing fogging and maintaining clear sight pictures. The polymer material won't scratch delicate lens coatings during contact.
