The Arisaka Offset Optic Mounting Base allows you to attach micro red dots to your rifle at either a 45° or 35° position to use in conjunction with your primary scope. This base by itself is machined from 6061-T6 aluminum and hardcoat anodized for durability. It is designed to attach directly to picatinny rails and is low profile enough to fit underneath most scope bodies allowing you to place it at your preferred position. The mount and plates can be reversed for left side use. The plates are sold separately and come in multiple different styles to fit your favorite red dot sight. When the rifle is canted, this mount keeps the red dot centered over bore and maintains a lower 1/3rd co-witness height.
