Butler Creek Flip-Open Objective Scope Cover, Size 30, 49.80mm

The Flip-Open Objective Scope Cover from Butler Creek (Butler Creek part no. 30300) is sized to the Size 30 fit chart entry, built for scopes with a 49.80mm objective bell. Molded from black polymer, it seals watertight and airtight over the objective lens 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.
