Butler Creek 30510 Flip-Open Objective Scope Cover 65.40mm Size 51 Black Polymer

The Butler Creek 30510 Flip-Open Objective Scope Cover delivers instant, one-thumb protection for the front lens of your rifle scope. Part of Butler Creek's iconic Flip-Open cover line, this objective cover is custom-fit to scope objective size 51 and slips directly over the objective bell with no tools required.

A light press of the hinged cover flips it open; release and it snaps shut, creating a watertight, airtight seal that keeps dust, debris, rain, and snow off the front lens of your optic. The non-slip, ergonomic polymer body is comfortable to actuate with a thumb even with gloves on, and the durable black polymer construction is built to handle years of field and range use.

Sized for a 65.40mm outer objective tube - Butler Creek's size 51 designation - the cover stays securely in place without sliding off, won't block your field of view when open, and installs in seconds. It's one of Butler Creek's most popular objective covers for hunters and shooters running rifle scopes that match this objective dimension.
