Butler Creek
A Butler Creek flip-open objective lens cover keeps your scope optics clean and dry in the field without slowing you down when it's time to take the shot. This Size 44 cover (59.90mm) is purpose-built for hunters and shooters who refuse to compromise on glass protection or performance. The custom-fit design seats firmly on your scope's objective bell with a friction mount that stays put through recoil and rough country, while the semi-O-ring seal blocks out dust and moisture so your glass stays crystal-clear from pre-dawn to pack-out.
The flip-open design is the whole point: spring-hinged caps swing away silently with a thumb, leaving you zero delay when an opportunity appears. No fumbling with caps, no noise that might spook game, no excuses. The ambidextrous design works whether you're right- or left-eye dominant, and the black polymer body is tough enough for serious use without adding bulk—it weighs less than an ounce. Butler Creek engineered this cover for the worst conditions: it's been tested down to –40°F, so it functions when cheaper covers get brittle and fail.
If you're running a precision hunting rifle, a target scope, or any mid-power optic where the objective is around 60mm, this cover is a small investment that prevents a costly failure. Dirt, rain, snow, and lens fog are inevitable in the field; a quality lens cover is not.

This is a Size 44 cover for 59.90mm objective lenses. Butler Creek's sizing is standardized across brands, but it's essential to check your scope's objective diameter against the size chart. If your scope has a different objective diameter, you'll need a different size.
Yes. The design is fully ambidextrous—the flip-open hinges and thumb operation work equally well from either side, regardless of your dominant eye or shooting stance.
The friction mount grips the objective bell of your scope with enough tension to stay put through handling, recoil, and field use, while remaining easy enough to remove or reposition when needed. The semi-O-ring provides additional grip and sealing.
The friction mount and semi-O-ring design create a watertight seal when closed. This keeps rain, snow, and moisture off your objective lens glass, protecting it from the elements.
