Butler Creek
The Butler Creek Flip-Open Objective Lens Cover in 27.80mm (Size 04) is a purpose-built lens protector for rifle scopes and hunting optics. If you're serious about shooting in the field—whether you're glassing from a ridge, waiting in a blind, or moving between positions—you need a cover that gets out of your way fast. This one flips open with a thumb and stays silent while doing it, so you're ready to shoot the moment an opportunity appears without spooking game or fumbling with a cap.
The custom-fit design seats snugly on a 27.80mm objective bell, anchored by water-tight friction mounts that don't require tools or permanent installation. Once seated, the semi-O-ring seal locks out dust and moisture, so your glass stays clear no matter what the weather throws at you—even in sub-zero conditions. At less than an ounce, it adds almost nothing to your rifle's weight or balance, and the open-and-close action is naturally ambidextrous, whether you're a right- or left-handed shooter.
Butler Creek's spring hinge mechanism is engineered to stay quiet; there's no metallic snap or clang that echoes across the mountainside. Whether you're hunting in wet, cold, or dusty environments, this cover keeps your objective lens protected during transport and storage, then springs into action when you need it.

This is a Size 04 cover designed for 27.80mm objective bells. Confirm your scope's objective diameter before ordering, as Butler Creek covers are custom-sized for a snug, secure fit. Refer to your scope's manual or specs if unsure.
The flip-open design allows you to open the cover with your thumb and keep your eye on the target. You don't have to fully remove it, making it quick to deploy when you're ready to take your shot.
The friction-mount design grips the objective bell securely without requiring screws, tools, or permanent modification. The water-tight seal is maintained by the semi-O-ring and the custom fit of the cover to your specific objective size.
Yes. The semi-O-ring creates an air-tight, water-tight seal to keep out dust and moisture. It's tested to –40°F, so it performs reliably in harsh weather and extreme temperatures typical of alpine and winter hunting.
