Butler Creek 20050 Flip-Open Eyepiece Cover 1.43" Size 05 Black

The Butler Creek 20050 Flip-Open Eyepiece Cover protects valuable optics from rain, snow, dust, and debris while maintaining instant access when targets appear. This Size 05 model fits 1.43"/36.40mm eyepieces with a secure, weatherproof seal that hunters and tactical shooters depend on in harsh conditions.

What Makes This Different

Unlike static lens caps that require removal and storage, this flip-open design stays attached to the scope for immediate deployment. The spring-loaded mechanism opens with thumb pressure and closes automatically when released. Butler Creek's precision-molded polymer construction provides years of reliable service without the weight penalty of metal alternatives.

Key Features

• Fits 1.43"/36.40mm eyepiece diameter scopes (Size 05 specification)
• Spring-loaded flip-open mechanism for one-handed operation
• Durable black polymer construction resists UV degradation and impact
• Weatherproof seal protects against moisture and debris infiltration

• Low-profile design won't snag on vegetation or gear
• Compatible with most variable and fixed power rifle scopes

Field performance remains consistent across temperature extremes from sub-zero hunting conditions to desert heat. The cover opens silently without alerting game, while the positive closure prevents accidental opening during transport. Professional guides and military personnel rely on this system because it functions reliably when optical clarity matters most.
