Arisaka Defense Offset Optic Mount

28 reviews

$25.00 – $125.00

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.

Description

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.

The Arisaka Offset Optic Mount is 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.

  • Plate 10: Leupold Delta Point Pro, JPoint, Shield RMS, SIG Romeo Zero
  • Plate 11: Aimpoint Micro T1/T2/H1/H2, SIG Romeo 4, 5 (not 5X), Holosun HS403 (not A), HS503, HS515, HS530
  • Plate 12: Aimpoint Acro

  • Plate 17: 1913 Picatinny Rail Adapter (40 degrees only, non-adjustable).
  • Plate 19: Holosun 407K, 507K

Do not exceed 20-inch lbs of torque on the screws that attach the optic to the plate.

Awesome company!

Fedex delivered my package to the wrong address. After they told me to kick rocks and accept my loss, milspec offered me a replacement or refund. Luckily I have a great neighborhood and the person who received my package brought it to me. Non the less. Amazing CS. The mount is perfect also.

Arisaka Defense offset RDS mount -SOLID

I use this offset RDS mount on an AR with a 1-8 LPVO. The transition from scope to my Romeo1 Pro is lightning fast. The mount places the red dot in the perfect location so that a simple flick of the wrist to tilt the rifle and the dot is right there.

Hardware is solid, coating is good, and I’m a lefty so yes it works on either side. I found the best place to mount on the rail was just far enough forward that the optic clears the scope knobs.

Great product

Arisaka Defense Offset Optic Mount

Just as advertised. Easy to set up as 35° or 45°, right or left hand.
I will definitely be ordering more for my other AR's.
