Monstrum Pro Series Flip-Up Scope Lens Covers
These Pro Series covers are designed to protect your glass with a rubberized sleeve that fits snugly around the scope tube.

Fit guidance emphasizes measuring the outer diameter of both eyepiece and objective bell to select the appropriate size, with a recommendation to choose the larger size if between measurements.

These covers require careful sizing by measuring the outside diameter of the eyepiece and objective bell.

The product includes one rubberized flip-up lens cover per package, and proper sizing is essential for a secure fit.

Buying Guide
Choosing the right scope flip caps involves sizing accuracy, material quality, and compatibility with your scope’s diameter. Consider these factors:
- Diameter compatibility: Measure the outside diameter of the eyepiece and objective bell to select a cover that fits snugly. When in doubt, choose the larger size as recommended by many manufacturers.
- Material and durability: Rubberized sleeves tend to offer better resilience and grip around the scope housing, reducing the chance of loosening or misalignment in rugged environments.
- Ambidextrous and ease of use: Some lids feature silent springs or ambidextrous designs to avoid spooking game and ensure quick action with minimal effort.
- Temperature and weather performance: Look for caps that tolerate a wide temperature range and resist moisture, dust, and debris ingress for consistent performance in various climates.
- Installation and maintenance: Ensure the cover is simple to install and replace. Periodically inspect the hinges and springs for wear or corrosion, especially after exposure to damp or harsh conditions.
- Brand and warranty: Reputable brands like Monstrum, Butler Creek, and Vortex typically offer durable builds and support, which can be beneficial for long-term use.
For multi-use scenarios, users may prefer a mix of eyepiece and objective bell covers to protect both ends of the scope. Always verify product packaging and sizing charts prior to purchase to ensure the correct fit for your specific model and tube diameter.
