Butler Creek 30280 Flip-Open Objective Scope Cover Size 28 48mm Black Polymer

The Butler Creek 30280 Flip-Open Objective Scope Cover is a spring-loaded protective cap built for rifle scopes with a 48mm (1.890") objective bell. As the Size 28 objective cover in Butler Creek's flagship Flip-Open line, it gives you fast, one-thumb operation so the lens is instantly ready when a target presents itself.

The cover is molded from a durable black polymer and slips directly over the objective end of the scope. An integrated semi-O-ring creates an airtight, watertight seal against the scope body, keeping dust, moisture, snow, and debris off the front element while the optic is stored or carried in the field. A positive detent holds the lid closed until you flip it open, and the same hinge keeps the lid out of the sight picture once deployed.

Butler Creek's slip-on fit is custom-sized to the objective diameter, so Size 28 grips a 48mm objective securely without wobble or rattles. There are no tools, rings, or clamps required, and the cover can be removed in seconds. Whether you are running a hunting rig, a tactical optic, or a varmint setup, this is a straightforward way to extend the life of your scope and keep the front lens clean in rough conditions.
