Trijicon AC32069 MRO Lower 1/3 Co-Witness Mount Black Anodized

The Trijicon AC32069 MRO Lower 1/3 Co-Witness Mount delivers precision positioning for the MRO red dot sight system. This black anodized aluminum mount provides the ideal height for co-witnessing with standard AR-15 iron sights while maintaining a comfortable cheek weld.

What Makes This Different

This mount positions the MRO optic at the lower 1/3 co-witness height, allowing shooters to see both the red dot and iron sights simultaneously in the lower portion of the optic window. Unlike absolute co-witness mounts that can create a cluttered sight picture, this configuration keeps iron sights visible but unobtrusive. The 7075-T6 aluminum construction provides military-grade durability while maintaining the precise tolerances required for consistent zero retention.

Key Features

• Lower 1/3 co-witness height for optimal sight picture clarity
• 7075-T6 aluminum construction with Type III hard anodizing
• Compatible with Picatinny and Weaver rail systems
• Torx screws included for secure, repeatable mounting
• Designed specifically for Trijicon MRO red dot sights
• Black anodized finish resists corrosion and wear
• Maintains MRO's waterproof seal integrity

This mount excels across multiple applications from tactical operations to competitive shooting. The lower 1/3 configuration proves particularly valuable in dynamic shooting scenarios where backup iron sights provide critical redundancy. Law enforcement and military users appreciate the ability to transition instantly to iron sights if the optic fails, while competitive shooters benefit from the unobstructed sight picture during rapid target engagement.
