Arisaka Defense Offset Plate, Trijicon Rmrcc For 1.9'' To 2.2'' Scope Mount

The Arisaka Defense Offset Plate for Trijicon RMRcc is a precision replacement optic plate engineered for shooters running larger scope mounts in the 1.9" to 2.2" height range. This plate works as part of the Arisaka modular offset mounting system, allowing you to mount a Trijicon RMRcc red dot sight at either 35 or 45 degrees offset from your primary optic—keeping your sight picture clean and your pistol grip hand ergonomic when you need it. If you're already invested in an Arisaka base, this plate gives you the upgrade path to swap in a different optic without replacing your entire mount.

The offset angle strategy solves a real problem on AR-pattern rifles: when your primary scope is chunky or sits high, a traditional co-witnessed red dot can sit too far from your eye or create shadow. By canting your rifle slightly, the offset red dot stays centered over the bore and holds a lower 1/3 co-witness height, giving you speed and accuracy without complicated mechanical compromise. The plate is reversible, so it works on left or right side rails depending on your setup.

Built from 6061-T6 aluminum and finished with MIL-spec hard coat anodize, this is the kind of precision hardware that handles duty-grade use. Arisaka's manufacturing tolerance and attention to detail mean zero wobble and zero excuses. If you already own an Arisaka base and want to try the Trijicon RMRcc platform, this plate is your path forward.

Frequently Asked Questions

Will this plate work with my current Arisaka base?

Yes, if you already own an Arisaka Offset Optic Mount base, this Trijicon RMRcc plate installs directly onto it. The modular design lets you swap plates to change your red dot optic without buying a new base.

What's the difference between the 35 and 45 degree offset positions?

The 35 degree angle positions the red dot closer to your primary scope for a more compact overall footprint, and works well with slimmer optics. The 45 degree angle provides more clearance away from larger, higher magnification scope turrets. The Arisaka base allows you to choose which position fits your setup best.

Can I use this plate on both left and right sides of my rifle?

Yes. The plate design is reversible, so you can mount it on either the left or right Picatinny rail on top of your receiver, depending on your dominant eye and shooting preference.

Do I need to buy anything else to use this plate?

Yes. This is a plate only. You will need the Arisaka Defense Offset Optic Mount base to attach this plate to your rifle's Picatinny rail. The base and plate work together as a system.
