ARISAKA Offset Optical Mount
The Arisaka Offset optical mount is a modular mounting solution that allows the operator to select a 35 or 45 degree offset for their red dot sight without additional components.
The 35-degree position brings the red dot sight closer to the thinnest scopes, while the 45-degree position provides extra clearance around wider turrets, or prominent laser modules.
The mount is reversed at 35 or 45 degrees by reversing the stem between the optical plate and the base during assembly. The mount's unique geometry correctly aligns the optics vertically with the bore and maintains a constant angle at 35 and 45 degrees.
Arisaka offers two turntable heights:
- Standard (for glasses with a height between 1.5" and 1.8")
- High (for glasses with a height between 1.9" and 2.2")
The base and optical plates can be reversed, making the mount completely ambidextrous.
It is recommended to choose the plate height that corresponds to your main optical height.

For example, if your scope is mounted in a 1.54" height mount, you would choose the standard height plate for your offset red dot sight. This ensures a consistent cheek position and a perfectly smooth transition between your primary optic and the offset red dot.
A wide selection of red dot sights is compatible with interchangeable optical plates.

Do not exceed a torque of 20 IN/Lbs on the screws that attach the optic to the plate.
The base and plates can be purchased separately or in combination, offering a possibility for future upgrades as operators acquire new red dot sights.
Arisaka offset mounting specifications:
Weight: 56 grams without optics.
Length: 2.54 cm for the base, which occupies three Picatinny slots (two recoil tabs and tightening screw).
Height: The base is 0.180" above the surface of the Picatinny rail.
The bracket is CNC machined from 6061-T6 aluminum and anodized MIL-A-8625 Type III.
Torx Plus IP20 and IP27 heads are included with each base.
Made in the USA.
Please refer to the instructions for torque values and mounting configuration.
All plates include new screws (if necessary) which we strongly recommend using.
The Leupold DPP 4 and 10 plates include extra long screws for attaching the optics to the plate which require a 2.5 mm Allen key.
