The Tenebraex Objective Lens Flip Cover & Adapter Ring provides military-grade physical protection for high-value tactical and hunting optics. Custom-engineered for objective bells with an outer diameter measuring 31.68mm to 32.18mm, this heavy-duty set shields delicate glass elements against rainfall, dust, trail debris, and high-impact scratches. The premium assembly contains an ultra-durable, non-brittle Tactical Tough™ thermoplastic flip cap paired alongside a rugged aluminum adapter ring that threads cleanly into your scope's objective housing. Its spring-loaded mechanism features internal locking detents, allowing you to flip the cover completely flat against the scope body to prevent accidental closure or visibility obstructions on the line. Fully rotatable to open in any direction, this elite protection system delivers reliable, split-second accessibility for outdoor enthusiasts operating in the harshest environments.
