The Butler Creek Flip-Open Objective Lens Cover in 34mm (Size 03) is a purpose-built lens protector designed for hunters and shooters who need reliable optic protection without the fumble. This black polymer cover mounts directly to your scope's objective lens and flips open with a quick thumb motion—no caps to lose, no clumsy cordage, and no delay when opportunity knocks. Whether you're glassing in rain, dust, or snow, you get fast, silent access to your sight picture the moment you need it.
The cover creates a watertight and airtight seal around your objective lens thanks to a semi-O-ring design that keeps moisture, dust, and debris away from your glass between shots. Custom-fit friction mounts grip your scope securely without tools or permanent modification, so installation is straightforward and removal leaves no marks. The spring-hinged design operates silently—crucial for hunting situations where even small sounds matter. Tested to perform in extreme cold down to –40°F, this cover doesn't stiffen up or fail when conditions get nasty.
Weighing less than an ounce and built from durable black polymer, the Butler Creek flip cover works equally well whether you're left- or right-handed. Unlike traditional threaded caps or tethered designs, this approach lets you keep both eyes on your target and your hands ready. It's the kind of accessory that disappears into your routine until you realize how much better your optics stay protected.
