The Arisaka RDM Aimpoint Micro 1.54" red dot mount is a precision-engineered optic accessory purpose-built for shooters running Aimpoint Micro optics on AR platforms and other tactical rifles. This 1.54" lower-third co-witness mount lets you keep your standard AR-height iron sights in play—visible in the lower third of your sight picture—so you maintain a complete backup aiming solution without sacrificing sight radius or ergonomics. Whether you're running a competition rifle, duty carbine, or hunting setup, this mount bridges the gap between optical and iron sights in a way that actually works in the field.
Built from 7075-T651 aluminum and finished with MIL-A-8625 Type III hard coat anodizing, the Arisaka mount is CNC-machined to tight tolerances and weighs just 3.0 ounces—light enough to matter on a rifle you'll carry all day, tough enough to handle hard use. The design is patented, and that engineering shows in the rock-solid repeatability and the way it sits flush without rattle. Made in the USA, it's the kind of component that rewards you with confidence once it's locked down.
The Arisaka RDM works with Aimpoint Micro T1 and T2 optics directly, and also accommodates other red dots sharing the same footprint—including Aimpoint H1/H2, Comp M5/M5S, Sig Romeo 4 and 5, Vortex Crossfire, and Holosun HS503/HS515/HS530. That versatility means you're not locked into a single optic choice, and if you ever upgrade or swap platforms, the mount remains a solid investment. At 1.54 inches, it's specifically the lower-third co-witness height, giving you the sight alignment that matters most for fast, accurate shooting under pressure.

The Arisaka RDM is designed for Aimpoint Micro T1 and T2 optics and will also work with other red dots using the same micro footprint, including Aimpoint H1/H2, Comp M5/M5S, Sig Romeo 4 and 5, Vortex Crossfire, and Holosun HS503/HS515/HS530.
At 1.54", this mount positions your red dot so that standard AR-height iron sights remain visible in the lower third of the optic lens. This means you can aim with your iron sights through the same window, giving you a true backup aiming system without removing the red dot.
The Arisaka RDM weighs just 3.0 ounces, keeping your rifle light and fast without compromising durability or precision.
Yes. The mount is CNC-machined and hard coat anodized in the USA using 7075-T651 aluminum and MIL-spec finishing.
