Arisaka Offset Optic Plate 6 for Acro/MPS – Precision Mounting Solution for Tactical and Competitive Shooting

The Arisaka Offset Optic Plate 6 is a precision mounting plate designed specifically for Aimpoint Acro red dot sights on AR15 rifles running offset optic setups. This plate is part of the modular Arisaka offset mounting ecosystem, letting you pair your Acro with an Arisaka base to position your red dot at an offset angle—35 or 45 degrees—without losing zero or co-witness height relative to your primary optic. Whether you're running a competitive 3-gun rig, a tactical carbine, or a precision AR setup, the Plate 6 gives you the flexibility to keep your Acro in the fight while maintaining lower 1/3 co-witness when the rifle is canted into your offset sight picture.

This is the standard-height plate, engineered for scope mounts in the 1.5" to 1.8" range. The plate itself is CNC machined from 6061-T6 aluminum and hard coat anodized to MIL-A-8625 Type III spec, so it'll handle the recoil and abuse of serious shooting. Because Arisaka's system is modular, you can swap plates as your optic lineup grows or upgrade without replacing the entire base—just grab the plate that matches your next red dot and go. The base and plates are reversible, so you can run offset left or right depending on your setup.

If you're building an offset dot mount for a compact Aimpoint Acro and want rock-solid precision without the weight penalty or complexity of traditional QD systems, the Plate 6 slots directly into the Arisaka ecosystem and gets you running fast. It pairs with an Arisaka Offset Optic Mount base (sold separately) and integrates into any AR15 top Picatinny rail.

Frequently Asked Questions

What red dot does the Plate 6 work with?

The Plate 6 is engineered specifically for the Aimpoint Acro. Do not use with other optics; each Arisaka plate is cut and spaced for its designated sight model.

Can I use this plate with a taller or shorter scope mount?

The Plate 6 is a standard-height plate, sized for scope mounts in the 1.5" to 1.8" range. If your scope mount is taller (1.9" to 2.2"), you'll need a different plate, such as Plate 12 (also for Acro in tall height). Verify your scope mount height before purchasing.

Do I need to buy the base separately?

Yes. The Plate 6 is the optic plate only. You'll need an Arisaka Offset Optic Mount base (sold separately) to attach to your AR15's top Picatinny rail. The base and plate work as a system to provide the 35 or 45 degree offset positioning.

Can I mount this plate on the left side of my rifle?

Yes. The Plate 6 and base are reversible, allowing you to configure your offset mount for left or right side use depending on your shooting preference or rifle setup.
