Butler Creek 20200 Flip-Open Eyepiece Scope Cover 1.77"/45.10mm Size 20 Black Polymer

The Butler Creek 20200 Flip-Open Eyepiece Scope Cover is the ultimate eyepiece protection for hunters and shooters. Custom fit to 1.77"/45.10mm eyepiece tubes (Size 20), this cover creates a watertight, airtight seal and opens with a touch of your thumb, so you can put your shot through the narrow window of opportunity in the most extreme conditions.

An ergonomic button with a non-slip surface operates the fast, flip-open design with a silent spring hinge to keep your eye on the target and not spook game. The black polymer construction is rugged enough for field use yet weighs less than an ounce, and has been tested to -40 degrees F for reliable performance in cold-weather hunting.

This slip-on eyepiece cover installs in seconds and stays put through rough handling, keeping dust, debris, rain, and snow off your scope's rear lens between shots.
