Butler Creek Flip-Open Objective Scope Cover, Size 43, 58.70mm

The Butler Creek Flip-Open Objective Scope Cover (Butler Creek part no. 30430) is a Size 43 objective lens cover custom fit to scopes with a 58.70mm objective bell, built to shield the glass between shots. Butler Creek molds this cover from tough black polymer and shapes it to snap open with a single touch of the thumb, so you’re never fumbling with a cap when a shot presents itself. A watertight, airtight seal keeps rain, snow, and trail dust off the lens until the moment you need a clear sight picture, and the hinge stays silent so the cover doesn’t spook game or draw attention on a stalk. It’s a simple, purpose-built way to protect a scope that sees real field use.

Key Specifications

• Custom fit for a 58.70mm 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 0.0938 lb, adding almost nothing to a scope’s overall weight.

• 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.
