Butler Creek 20035 Flip-Open Eyepiece Cover 1.39" Size 03 Black

The Butler Creek 20035 flip-open eyepiece cover protects rifle scope lenses from dust, moisture, and impact damage while maintaining instant access for target acquisition. This size 03 model fits eyepieces measuring 1.39 inches (35.30mm) in diameter, providing a secure weatherproof seal that opens with finger pressure.

What Makes This Different

Unlike fixed lens caps that must be removed and stored, this flip-open design stays attached to the scope during use. The spring-loaded hinge mechanism opens with light pressure from the shooting hand, eliminating fumbling with separate caps in critical moments. Butler Creek's polymer construction resists cracking in temperature extremes from -40°F to 160°F, outlasting rubber alternatives that become brittle or sticky over time.

Key Features

• Flip-open design allows instant lens access without removing cap
• Fits 1.39-inch (35.30mm) diameter eyepieces precisely
• Durable black polymer construction resists UV degradation
• Spring-loaded hinge maintains positive open and closed positions
• Weatherproof seal protects against moisture and debris
• Low-profile design won't snag on gear or vegetation
• Compatible with most variable and fixed power rifle scopes

Field performance remains consistent across hunting, tactical, and competitive shooting applications. The cover opens silently without alerting game, while the secure closure prevents accidental opening during transport. Temperature cycling from cold morning hunts to hot afternoon ranges won't affect the hinge mechanism or sealing properties.
