Butler Creek Flip-Open Eyepiece Scope Cover, Size 17, 1.67 in.

The Flip-Open Eyepiece Scope Cover from Butler Creek (Butler Creek part no. MO20170) is sized to the Size 17 fit chart entry, built for scopes with a 1.67-inch (42.50mm) opening. Molded from black polymer, it seals watertight and airtight over the eyepiece to keep the elements off your glass, then opens instantly with a single thumb press when you need to shoot. Butler Creek designed the hinge to operate silently, a detail hunters glassing game at close range will appreciate, and the whole cover adds almost no weight to your rifle. It’s built to protect a scope’s glass through genuine field and hunting use, not just sit in a range bag.
