Butler Creek 20180 Flip-Open Eyepiece Scope Cover 1.70"/43.20mm Size 18 Black Polymer

The Butler Creek Flip-Open Eyepiece Scope Cover delivers rugged, weatherproof protection for your scope's ocular lens with the convenience of one-finger operation. Part of the trusted Butler Creek Flip-Open line, this cover is custom-sized at Size 18 to fit scopes with 1.70"/43.20mm eyepiece tubes and installs in seconds with a simple slip-on fit - no tools or gunsmithing required.

The spring-loaded cap flips open at the touch of a finger and snaps closed to create a watertight, airtight seal that keeps rain, snow, dust, and debris off your lens in the field. Molded from tough, weather-resistant black polymer, the cover shrugs off impact, temperature swings, and hard use on hunting rifles and tactical optics without adding meaningful weight.

Whether you're stalking a buck through wet timber or running drills on the range, the Butler Creek 20180 keeps your eyepiece clear, clean, and protected so you never lose sight of your target.
