Arisaka Rdm Aimpnt Micro 2.26" Fde

The Arisaka Defense RDM Aimpoint Micro mount at 2.26" height is a precision optic mount engineered for shooters running red dot sights on modern rifles. This mount positions your Aimpoint Micro T1 or T2—or compatible optics like the H1/H2, Comp M5/M5S, Sig Romeo 4 and 5, Vortex Crossfire, and Holosun HS503/HS515/HS530—at an optimal sight line that keeps your lower-third iron sights visible through the window beneath the optic. If you're pairing this with a Unity FAST FTC magnifier mount, the 2.26" height creates a seamless co-witness setup.

Built tough for duty and duty-grade shooting, this mount is CNC machined from 7075-T651 aluminum—the same alloy used in aerospace and high-stress applications—then hard coat anodized to MIL-A-8625 Type III spec for corrosion resistance and durability. At 3.2 oz, it adds minimal weight to your upper receiver while delivering rock-solid repeatable mounting. Made in the USA, the Arisaka RDM mount represents the kind of no-nonsense engineering that works when your gear needs to work.

Whether you're building a 3-gun rig, a duty carbine, or a modern hunting setup, the 2.26" height strikes a practical balance: it clears most handguards and gas tubes, gives you adequate cheek weld, and preserves your iron sight picture as a backup. The FDE finish blends with most modern rifles and gear while resisting fingerprints and wear.

Frequently Asked Questions

What red dot optics does this mount fit?

The Arisaka RDM mount is designed for Aimpoint Micro T1 and T2 optics. It also accommodates other red dots sharing the same footprint, including Aimpoint H1/H2, Aimpoint Comp M5/M5S, Sig Romeo 4 and 5, Vortex Crossfire, and Holosun HS503/HS515/HS530.

Will my iron sights still be visible with the 2.26" height?

Yes. The 2.26" height positions your iron sights in the lower third of the optic lens window, and standard AR-height irons are visible through the mounting window directly below the optic. This setup is ideal if you want to maintain a usable backup sight picture.

Is this mount compatible with magnifier mounts?

The 2.26" height matches up with the Unity FAST FTC Magnifier Mount, making it a natural pairing for shooters running magnification behind their red dot.

Is this mount made in the USA?

Yes. The Arisaka RDM mount is CNC machined from 7075-T651 aluminum and finished to MIL-A-8625 Type III hard coat anodize specifications in the USA.
