Details

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.

Features:
  • Centered over bore
  • Lower 1/3rd co-witness height
  • Adjustable between 35° and 45°
  • Machined from 6061-T6 aluminum
  • Hardcoat anodized
  • Occupies three slots
  • Weight: 1.9 oz.

Must have for BUS

by -

Tucks neatly under my LVPO, amazing craftsmanship you can expect from Arisaka Defense. The best part is it does advertised, sits directly in line with the bore axis.
Mounted under vortex and on SOLGW M76

Excellent mount

by -

Excellent piece. Well made, rock solid, would highly recommend.

High quality

by -

Well machined part. The option for 30 or 45 degrees actually makes a big difference and nice to have.

Worth it if…

by -

The mount is worth every penny to me because I absolutely had to have a 35 degree mount option. A 35 degree grip angle is just more comfortable for me when I shoot, especially when it’s an AR pistol platform.

Awesome product with flexibility

by -

I had purchased a different set up and it really didn’t work for my application. Saw this product and watched some video’s reviewing it and immediately ordered. So glad I did as having the flexibility to do a 45 or 35 degree was awesome. Actually saved me money by returning the other two items since this and the mounting plate ended up together cheaper then the other configuration I had. Quality Solid product and my go to for an offset optic going forward. Shipping was fast and all around impressed.

Solid

by -

Even if I drop my rifle on the offset red dot, this holds solid. Love it.

Durable and holds zero perfectly.

Durable and holds zero perfectly.

Highly recommended

I got this to replace a T-Rex Arms offset mount — with that I could never get my Holosun 509T zeroed because I ran out of elevation and windage adjustment.

Tne Arisaka on the other hand works perfectly.

As expected

by -

It's Arisaka, what did you expect? It locks on tight, holds zero, and sits far enough off the weapon to not get lost in the turrets on my LPVO. Definitely worth every penny!

Very Low, Good Return To Zero

I put one on a scoped rifle about 2 years ago because even at 1x, fast close target acquisition is hard for me with a scope. Then decided to test it on my competition PCC for those pesky left hand fault line shots. I worked really well for me, so I bought another one. I predict I will end up with at least one more.
