Arisaka Defense
The Arisaka Offset Optic Plate 5 for Aimpoint is a precision mounting solution designed for shooters running Aimpoint Micro (T1, T2, H1, H2) red dots, SIG Romeo 4 and 5, or Holosun HS403, HS503, HS515, and HS530 optics on AR15s with magnified scopes. This modular plate pairs with the Arisaka Defense offset optic base to mount your red dot at either 35 or 45 degrees, positioning your backup or co-witness optic where you need it—without the bulk or the backup battery drain of a permanent one-sight setup.
Built from 6061-T6 aluminum and MIL-spec hard coat anodized, Plate 5 is engineered for the durability your rifle demands. Whether you're setting up a precision DMR, a hunting rifle with a primary scope, or a duty carbine, this plate lets you keep your red dot accessible without compromising sight picture through your primary optic. The 35-degree angle works with standard-height scope mounts (1.5" to 1.8"); the modular design means you can upgrade plates later if your optic collection grows.
The base and plates are sold separately or together, so you can build your offset setup piece by piece or swap plates as your gear evolves. CNC machined and hard anodized for zero wobble, the Arisaka system maintains the lower 1/3 co-witness height that keeps you in the fight when canting the rifle, and the plates are reversible for left or right side mounting.
