The Butler Creek Flip-Open Objective Scope Cover, Size 51 (Butler Creek part no. 30510) protects the front lens of your scope with a custom-fit cap that opens with a touch of the thumb. Butler Creek uses silent spring hinges so the cover will not spook game, and a custom-fit friction mount that is water-tight on the scope. An air-tight semi-O-ring keeps dust and moisture off the glass. Match the size number to your objective, since each size is made for a different lens diameter. The rugged polymer build stands up to hard field use.
