Product Summary

The Patent Pending Arisaka Offset Optic Mount is a modular mounting solution that allows the user to select a 35 or 45 degree offset position for a red dot sight without requiring additional components. The 35-degree position brings the red dot sight up closer to slimmer, smaller scopes, while the 45-degree position provides additional clearance around wider turrets or larger, higher magnification scopes.

  • Designed to be attached to the top Picatinny rail of an AR15 rifle.
  • When the rifle is canted to make use of the offset red dot sight, the optic remains centered over the bore and maintains a lower 1/3 co-witness height.
  • The base and optic plates can be reversed, allowing for use on the left or right side.
