The Butler Creek Flip-Open scope cover size 14 is a slip-on eyepiece cover sized for an ocular housing measuring 1.605 inches, or 40.8 mm (Butler Creek part no. MO20140). Butler Creek builds it to seal the eyepiece against water and air and to pop open at the touch of a thumb, so the lens stays protected right up until the shot. Silent spring hinges keep the lid from making noise that could spook game, and the cover works the same from either side. At under an ounce, it adds no meaningful weight to the rifle. It is a simple, proven way to keep moisture and dust off the eyepiece through a long day in the field.

Key Specifications

• The size is 14, which Butler Creek’s measurement chart matches to an eyepiece outside diameter of 1.605 inches (40.8 mm).
• It is an eyepiece cover, made for the ocular end of the scope rather than the objective bell.
• The cover is a slip-on design held by a custom-fit friction mount, so no tools or clamps are needed to install it.
• The flip-open lid pops up at the touch of a thumb, which keeps your eye on the target as you get ready to shoot.
• The lid rides on silent spring hinges, which Butler Creek uses so opening the cover will not spook game.
• Its friction mount creates a watertight seal against the eyepiece, keeping rain off the ocular lens.
• An airtight semi-O-ring keeps dust and moisture out of the space between the cap and the lens.
• Operation is ambidextrous, so left- and right-handed shooters flip it open the same way.
• Weight is under one ounce, light enough that it will not change how the rifle carries or balances.

Frequently Asked Questions

How do I know size 14 fits my scope? Measure the outside diameter of the eyepiece housing with calipers or a ruler. Butler Creek lists size 14 at 1.605 inches (40.8 mm), and if your scope falls between two sizes the company recommends choosing the smaller size, with a wrap of electrical tape to help achieve a snug fit.

Does this cover go on the front or the rear of the scope? This is the eyepiece version, made for the rear, ocular end of the scope. Butler Creek sizes its objective covers on a separate chart.

Will opening it make noise? Butler Creek fits the Flip-Open with silent spring hinges so the lid opens quietly, and the cover can be flipped with either thumb.
