Butler Creek’s Flip-Open Objective Scope Cover (Butler Creek part no. 30150) is molded specifically for scopes with a 39.60mm objective bell, matched to the Size 15 listing on Butler Creek’s fit chart. Cut from durable black polymer, the cover snaps closed over the objective lens to keep weather and grit off the glass, then flips open with one touch of the thumb when it’s time to shoot. Butler Creek engineers the hinge to move silently, so hunters glassing for game don’t give away their position with a loud cap, and the seal is rated watertight and airtight for use in genuinely rough conditions. It’s an inexpensive way to keep a hunting or field scope’s glass protected without slowing you down.

Key Specifications

• Molded as Butler Creek’s Size 15 fit-chart listing, sized to a 39.60mm objective bell.
• Custom fit for a 39.60mm 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 0.0313 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.
