Butler Creek 30310 Flip-Open Objective Scope Cover 50.70mm Size 31 Black Polymer

The Butler Creek Flip-Open #31 Objective Scope Cover is a spring-loaded objective lens cover custom-fit to protect the front lens of a hunting or tactical rifle scope. Sized as Size 31, this cover fits objective bell diameters from 1.960" to 1.998" (50.70mm), giving shooters a precise factory-style fit on popular mid-sized optics.

Molded from a pliable black polymer, the one-piece cap creates a watertight, dustproof seal around the objective bell thanks to an integrated O-ring and a secure friction-fit slip-on mount. Silent spring hinges let the cover flip open with a quick push of the thumb and stay clear of the sight picture, so it never interferes with cheek weld, eye relief, or follow-up shots.

A simple, field-proven upgrade, this Butler Creek objective cover shields the lens from dust, rain, debris, and incidental impact during transport, storage, and hunting in adverse weather. Installation is tool-free and the cover stays firmly anchored to the scope until deliberately flipped open, making it a must-have accessory for any rifle scope in the 50.70mm objective size range.
