Butler Creek Flip-Open Objective Scope Cover - 1.387"/35.2mm MFG 30050 Size 05

The Butler Creek Flip-Open Objective Scope Cover in 1.387"/35.2mm (Model 30050, Size 05) is an essential accessory for anyone who trusts optics in the field—whether you're glassing from a boat, scanning coastal flats, or hunting from a blind. Objective lens caps are non-negotiable when you're serious about protecting your scope investment during transport, storage, and rough water conditions. This flip-open design keeps your lens clean and damage-free without requiring you to remove the cap during the critical moment when you need your sight picture ready.

Butler Creek's flip-open mechanism is engineered for fast deployment and one-handed operation, critical when you're managing a rod, paddle, or weapon simultaneously. The 1.387-inch (35.2mm) diameter opening accommodates standard objective lenses across most mid-range magnification scopes, and the hinged cover stays tethered to the scope body so you'll never lose it overboard or in brush. The durable polymer construction resists saltwater corrosion, UV degradation, and impact—tough enough for years of marine and field use while remaining lightweight at just 0.05 lbs.

This Size 05 cover fits most mainstream hunting and tactical scopes in the 3–9x and 4–12x magnification range, making it one of the most versatile objective cap options available. If your scope's objective bell measures approximately 1.387 inches, this cap will seat flush and provide reliable protection. Install it by simply snapping it onto your objective housing—no tools required—and you're ready for whatever conditions you encounter, from saltwater spray to muddy riverbanks.
