Butler Creek Flip-Open Eyepiece Cover - Size 14 (1.60"/40.80mm), Black Polymer (Model 20140)

The Butler Creek Flip-Open Eyepiece Cover (Model 20140) is a durable polymer lens protector sized for 1.60-inch (40.80mm) eyepieces—a quick-access solution that keeps dust, moisture, and weather off your scope's optics without slowing you down in the field. This size 14 cover uses spring-tension engineering: a light finger tap flips it open and automatically springs out of your sight picture, so you're never fumbling with a lens cap during the moment that matters. Whether you're hunting, shooting long-range, or running drills at the range, unprotected scope glass is an expensive mistake; this small, lightweight accessory is the insurance policy that costs almost nothing.

Built from tough black polymer, the flip-open design eliminates the lost-cap problem and the distraction of removing a cover by hand. The spring mechanism is simple and reliable—no springs to break or moving parts to jam. It's weatherproof and dust-proof by virtue of its snap-fit seal, meaning your objective and eyepiece stay clear and dry in rain, snow, dust, or humidity. The cover attaches securely and won't rattle loose in a pack or vehicle.

Butler Creek covers are sized by eyepiece or objective diameter, and this model fits 1.60-inch tubes. If you need to protect your objective lens, note that objective and eyepiece covers are sold separately, so you can outfit both ends of your scope or just the one that takes the most abuse. For hunters and shooters serious about optics care, a set of both eyepiece and objective covers is the bare minimum—your glass will thank you for it.

Frequently Asked Questions

Will this cover fit my scope's objective lens?

This is an eyepiece cover only. Objective covers are sold separately. If you have a 1.60-inch objective bell, you would need to purchase an objective cover (also size 14) to protect that end of your scope.

How do I know if size 14 is right for my scope?

Measure the outside diameter of your scope's eyepiece tube. If it measures 1.60 inches (40.80mm), size 14 is your cover. Butler Creek offers multiple sizes, so confirm your measurement before ordering.

Will the cover stay on during normal hunting and shooting?

Yes. The cover is designed to fit securely and will not rattle loose during recoil or movement. The spring-flip mechanism keeps it firmly attached until you flip it open.

What's the advantage of flip-open over a regular threaded cap?

The flip-open design means you never have to remove and store or lose a lens cap. One finger-tap opens it and springs it automatically out of your field of view—faster and more reliable than fumbling with a traditional cap in the field.
