Butler Creek Flip-Open Objective Scope Cover, Size 27, 46.70mm

This Butler Creek Flip-Open Objective Scope Cover (Butler Creek part no. 30270) is a Size 27 cover, custom molded in black polymer to fit scopes with a 46.70mm objective bell. Butler Creek built the line around a fast, silent, flip-open hinge, so a single push of the thumb clears the objective lens for a shot without a fumbled cap costing you the moment. The cover forms a watertight, airtight seal over the glass between uses, keeping out rain, snow, and dust on a long day afield. It’s a small, low-cost accessory that solves a real problem for anyone running a scope outside a climate-controlled range.

Key Specifications

• Molded as Butler Creek’s Size 27 fit-chart listing, sized to a 46.70mm objective bell.
• Custom fit for a 46.70mm objective bell, matching the scope’s own measurement rather than a generic universal size.
• Molded from black polymer for a durable, lightweight cover that won’t rust or corrode.
• Uses a slip-on mounting style, no tools or adhesive needed to install or remove it.
• Forms a watertight, airtight seal over the objective lens, keeping rain, snow, and dust off the glass.
• Opens with a single touch of the thumb via a spring-loaded, flip-open lid.
• The hinge operates silently, so opening the cover won’t spook game or give away your position.
• Ships at a featherlight 0.05 lb, adding almost nothing to a scope’s overall weight.
• Cold-weather tested to -40 degrees F, holding up through genuine winter field conditions.
• Butler Creek builds these to a fit tolerance of 0.01 inch under to 0.025 inch over the listed measurement, so the seal stays snug.
