The Butler Creek 20110 Flip-Open Eyepiece Scope Cover is built to protect your optic’s eyepiece with a precise, custom fit. Designed for a 1.55" (39.40mm) outside diameter eyepiece, this Size 11 cover forms a watertight, airtight seal that keeps dust, moisture, and debris off your glass while remaining lightweight and unobtrusive on the rifle.

This slip-on polymer cover uses an ergonomic non-slip button for fast, one-touch opening, and a silent spring hinge so you can stay focused on the shot without disturbing game. Weatherproof construction and testing down to -40°F make it a dependable choice for hunters and shooters who need clear optics in harsh conditions. Butler Creek’s long-standing reputation for practical, durable scope accessories is reflected in this simple, effective eyepiece cover.
