Monstrum Pro Series Flip-Up Eyepiece Cover 43-48 mm
Monstrum Pro Series Scope Lens Covers are designed to protect glass from dust and impact when the lens isn’t in use. The rubberized sleeve adheres snugly to the scope tube, offering improved resiliency over previous formulations. Before purchasing, measure the outer diameter of both the eyepiece and the objective bell to select the correct lens cover size. If you are between sizes, the larger option is recommended for a reliable fit.
Key features relevant to this product include durable rubberized sleeves and guidance on sizing, ensuring a secure fit across common 43-48 mm eyepiece ranges. This set focuses on protecting the eyepiece area, where dust and moisture can compromise view clarity during rapid close-range shooting or hunting in challenging weather.
Monstrum Rubberized Flip-Up Rifle Scope Lens Covers (Eyepiece 37-42 mm)
This Monstrum option emphasizes precise sizing to avoid mismatches. A sizing chart and video accompany the product to ensure you measure the OUTSIDE diameter of your scope eyepiece and objective bell correctly. The guide notes that sizing is based on the outside diameter of your scope housing, not the objective lens diameter. Each package includes one Rubberized Flip-Up Lens Cover, making it a practical choice for single-scope setups or as a spare.
Pros include clear size guidance, straightforward installation, and a comfortable rubberized feel that resists wear. Potential considerations involve ensuring you do not choose a size based on the lens diameter alone, as the outside diameter of the housing drives the fit. This option suits shooters needing a dependable eyepiece cover without bulky added features.
Monstrum Pro Series Flip-Up Eyepiece Cover 37-42 mm
This variant targets mid-sized eyepieces, offering the same durable rubberized sleeve and sizing guidance as other Pro Series covers. As with the 43-48 mm version, careful measurement of both ends of the scope is advised to ensure a proper fit. The emphasis is on protecting the eyepiece without adding excessive bulk, making it a practical option for sport shooters and hunters who frequently switch targets or engage in rapid-fire scenarios.
Monstrum Pro Series Flip-Up Scope Lens Covers (Objective Bell 43-48 mm)
Designed to shield the objective end, this cover mirrors the Pro Series approach to durability and snug fit. It provides protection for the front element where debris and rain are most likely to cause issues. The same sizing guidance applies: measure the outside diameter of the objective bell and eyepiece to determine the correct range. When in doubt, selecting the larger size can help ensure a secure fit in real-world conditions.
Monstrum Rubberized Flip-Up Rifle Scope Lens Covers (Eyepiece 43-48 mm)
This variant offers coverage for slightly larger eyepiece diameters, with sizing notes that stress measuring the outside diameter of the scope housing. The included covers are designed to fit snugly, reducing the risk of accidental removal or misalignment during movement. As with other Monstrum models, the emphasis remains on maintaining glass integrity in variable outdoor scenarios, from rain to dusty fields.
Monstrum Rubberized Flip-Up Rifle Scope Lens Covers (Objective Bell 37-42 mm)
This cover focuses on the objective-end protection with the same careful sizing framework. It is intended for users who want consistent performance across both eyepiece and objective ends. Remember that sizing is determined by the outside diameter of the scope housing, not the lens diameter, to ensure a proper fit across environments and mounting configurations. A single package includes one cover, suitable for spare or backup use in rugged field conditions.
Monstrum Ultra Series Flip-Up 43-48 mm Eyepiece Cover
The Ultra Series emphasizes sizing clarity and durability for the 43-48 mm range.

This option is well-suited for shooters who demand repeatable performance in challenging outdoor conditions while keeping optics clean and protected.

Butler Creek’s Flip-Open design emphasizes silent, ambidextrous operation with hinges that open instantly on demand. It also includes clear sizing guidance and a quick-access mechanism that reduces the time needed to view through the scope in fast-paced scenarios. This option is suitable for hunters and competitors who require reliability and a low-profile cap that won’t spook game.
Buying Guide: Key Purchase Considerations
- Size and fit: Always measure the outside diameter of the scope housing (eyepiece and objective bell) to select the correct range. If you’re between sizes, opt for the larger one to ensure a secure fit.
- End coverage: Decide whether you need protection for the eyepiece, the objective bell, or both. Some sets offer separate covers for different parts of the scope.
- Material and durability: Rubberized sleeves provide resilience and a snug fit, while some models emphasize silent operation and quick action hinges for rapid reuse.
- Weight and bulk: Flip-up covers are designed to be lightweight, but consider the added bulk in compact setups or when using magnified optics in tight enclosures.
- Installation and maintenance: Check if covers require tools or special care. Regular cleaning helps maintain the seal and prolongs life.
- Compatibility: Ensure the selected cover matches the specific diameter ranges listed by the manufacturer and is not based on lens diameter alone.
- Field conditions: For rainy, dusty, or muddy environments, prioritize covers with robust rubberized sleeves and proven reliability under environmental stress.
In evaluating flip-up lens covers, consumers should balance fit, protection level, and ease of use. Monstrum models emphasize a consistent sizing framework and durable rubberized materials, while Butler Creek adds a quick-open, ambidextrous design for fast response. For most field applications, choosing a combination that covers both eyepiece and objective ends in the appropriate diameter range provides comprehensive protection without adding unnecessary weight.
