Butler Creek Flip-Open Objective Scope Cover - 1.7"/43.2mm MFG 30200 Size 20

The Butler Creek Flip-Open Objective Scope Cover in 1.7"/43.2mm (MFG 30200 Size 20) delivers reliable lens protection engineered for hunters and precision shooters who cannot afford optical failure in critical moments. This custom-fit objective scope cover creates a watertight, airtight seal that safeguards your optics from rain, dust, fog, and salt spray—environmental hazards that degrade glass clarity and internal coatings when left unprotected.

The flip-open design uses silent spring hinges that move without metallic noise, allowing you to expose your lens in seconds without alerting game at close range. The thumb-activated mechanism requires minimal hand movement, meaning your primary grip and shooting position remain unchanged when transitioning from covered to ready. Butler Creek's size 20 objective cover fits 1.7-inch diameter objective lenses, making it compatible with mid-range and long-range scope configurations used on rifles from .308 Winchester to magnum calibers. The compact footprint—2.8 x 1.55 x 4.9 inches—adds negligible weight (0.03 lbs) and bulk to your rifle setup.

This accessory is essential for hunters navigating variable weather, backcountry expeditions where optical degradation is not an option, and tactical shooters who maintain gear standards between string sessions. Precision rifle competitors, whitetail hunters working fog-prone valleys, and long-range hunters in coastal or wet climates all depend on objective covers to preserve lens coatings and internal clarity. The Butler Creek flip cover bridges the gap between bare-glass vulnerability and heavy hard cases, providing field-ready protection without sacrificing rapid target acquisition when opportunity arrives.
