Arisaka Rdm Trijicon Mro 1.7"

The Arisaka Defense Rdm Trijicon Mro 1.7" optic mount is purpose-built for operators who demand repeatable, rock-solid performance in mounting compact red-dot sights to mil-spec Picatinny rails. This precision adapter bridges the gap between the Trijicon MRO platform and standard tactical rails, delivering the co-witness height and mechanical reliability that law enforcement, military, and competitive shooters depend on. Designed with a 1.7-inch optic centerline, this mount positions your sight at optimal viewing geometry while maintaining lower-third co-witness capability with standard combat iron sights.

Engineered by Arisaka Defense—a manufacturer respected across SOF communities for uncompromising build quality—this RDM (Rapid Deployment Mount) variant features a Type III hard-anodized finish that resists corrosion, scratches, and environmental degradation. The anodized aluminum construction provides a perfect balance of rigidity and weight control, ensuring zero shift during recoil cycles while adding negligible mass to your firearm. Arisaka's no-nonsense design eliminates play and flex, critical for maintaining the optical zero through thousands of rounds and field deployments. The Picatinny interface uses standard 1913 mounting, guaranteeing compatibility with virtually any modern tactical platform.

This mount excels on AR-15 uppers, short-range battle rifles, and any weapon system running the Trijicon MRO red-dot—one of the fastest-growing optics in military and law enforcement arsenals due to its exceptional battery life, rugged construction, and parallax-free performance. Installation is straightforward: secure the mount to your rail via the standard Picatinny slot, then attach your MRO using the optic's integrated mounting footprint. Weighing just one pound, it introduces virtually no balance shift. Whether you're building a duty rifle, SBR, or precision carbine, the Arisaka Rdm Trijicon Mro 1.7" mount delivers the simplicity and durability required by professionals.
