The Butler Creek 30170 Flip-Open Objective Scope Cover Size 17 is built to keep your optic’s objective lens clean, dry, and ready when it matters. Custom fit for 40.90mm outside diameter objectives, it uses a friction-mount, watertight and airtight seal that stays put on the scope while the fast flip-open lid clears your sight picture with a simple thumb push. The lightweight polymer body and silent spring hinge are designed for dependable performance even in harsh weather and temperatures tested down to -40 degrees Fahrenheit.

This objective cover is ideal for hunters and target shooters who need instant access to a clear optic without fumbling with loose caps or exposing the lens to dust, moisture, and debris. Its ambidextrous flip tabs and slip-on style make it easy to use from field positions or at the range, while the rugged construction helps protect valuable glass from everyday knocks. Backed by Butler Creek’s long-standing reputation for practical, durable scope accessories, this Flip-Open Objective Scope Cover is a simple upgrade that adds real protection and convenience to your setup.
