The Arisaka Defense Plate #7 is a replacement optic plate designed for the modular Arisaka Offset Optic Mount system on AR15 platforms. This tall-height plate fits scope mounts in the 1.9" to 2.2" range, making it the right choice when you're running larger optics with taller turrets or higher magnification glass. It's engineered to work with a specific set of popular red dot sights, giving you flexibility to swap optics without replacing the entire mounting solution.
The plate is CNC machined from 6061-T6 aluminum and finished with MIL-A-8625 Type III hard coat anodize for durability in the field. Because Arisaka's system allows base and plate reversal, you can configure this for left or right side mounting depending on your setup and shooting preference. If you already own an Arisaka base, purchasing just the plate gives you a cost-effective way to adapt the mount for different red dot optics as your kit evolves.
Plate #7 is compatible with Docter, Eotech MRDS, Insight, Meopta, Vortex Venom/Viper, and Burris Fastfire III red dot sights. The modular design means you're not locked into one optic choice—swap plates, upgrade optics, and keep the base. This approach makes sense for serious shooters who experiment with different setups or plan to repurpose the mount across multiple rifles.

Yes, the Plate #7 is a component of the modular Arisaka Offset Optic Mount system and requires the base unit (sold separately) to function. The base attaches to your AR15's top Picatinny rail and allows you to change plates as you swap optics.
Yes. The Arisaka system allows you to reverse both the base and plates, so you can configure Plate #7 for either left or right side mounting depending on your needs.
