Setup and Installation
The Alumina Flip Back Lens Covers are designed for straightforward installation on compatible Leupold riflescopes. Ensure your scope was built after 2004 and has a 40mm objective lens for proper fitment.
- Identify Covers: Distinguish between the objective lens cover (larger, for the front of the scope) and the eyepiece cover (smaller, for the rear of the scope).
- Thread onto Objective: Carefully align the threads of the objective lens cover with the threads on the front of your riflescope's objective bell. Gently rotate clockwise to screw the cover into place. Do not overtighten.
- Thread onto Eyepiece: Similarly, align the threads of the eyepiece cover with the threads on the rear of your riflescope's eyepiece. Screw it into place clockwise until snug.
- Adjust Orientation: The round objective and ocular models can be rotated after installation to allow them to open in any desired direction (e.g., upwards, downwards, or to the side) for optimal clearance and user preference.

Operating Instructions
Operating the Alumina Flip Back Lens Covers is designed for speed and efficiency.
- Opening the Covers: To open, simply apply light pressure to the edge of the cover and flip it upwards or downwards, depending on its installed orientation. The covers are designed to snap open quickly and quietly.
- Closing the Covers: To close, gently push the cover back down until the internal neodymium magnets engage, securing it firmly in the closed position. Ensure a complete seal is made to protect against elements.
- Low-Profile Position: When open, the covers are engineered to lie flat against the scope body, minimizing obstruction and preventing interference with your line of sight or other accessories.
Maintenance
Proper maintenance will ensure the longevity and optimal performance of your lens covers.
- Cleaning: Wipe the exterior of the covers with a soft, clean cloth to remove dust and debris. For stubborn dirt, a slightly damp cloth can be used. Avoid abrasive cleaners or solvents.
- O-Ring Inspection: Periodically inspect the triple O-rings for any signs of wear, cracking, or damage. Damaged O-rings can compromise the waterproof seal. If replacement is needed, contact Leupold customer support.
- Hinge Functionality: Ensure the hinge mechanism operates smoothly. If it becomes stiff, a small amount of silicone-based lubricant can be applied sparingly to the pivot points.
- Storage: When not in use, store the lens covers in a clean, dry environment, ideally attached to the riflescope to prevent loss or damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Cover does not close securely. | Debris obstructing magnets or worn magnets. | Clean the magnet areas. If magnets are worn, contact Leupold for service. |
| Cover is difficult to open or close. | Dirt in hinge mechanism or lack of lubrication. | Clean the hinge area. Apply a small amount of silicone lubricant to the pivot points. |
| Water or dust ingress. | Damaged or improperly seated O-rings. | Inspect O-rings for damage. Ensure covers are fully threaded and snug. Contact Leupold for O-ring replacement if necessary. |
| Cover does not fit scope. | Incorrect scope model or objective size. | Verify your riflescope model and objective lens size. This kit is for post-2004 Leupold scopes with 40mm objective lenses. |
