The Patented Arisaka Offset Optic Mount lets you pick a 35 or 45-degree angle for your red dot sight without needing extra parts. If you choose the 35-degree angle, your red dot sight will be closer to smaller scopes. But if you go for the 45-degree angle, it gives you more space around big turrets.
The mount comes in two sizes: the standard one is from 1.5" to 1.8" tall, and the tall one is from 1.9" to 2.2" tall. You can switch the base and optic plates, so it works for both right and left-handed shooters. It's best to match the plate size with your main scope size to make sure you're comfortable and can switch easily between your main scope and the red dot.
It also supports many red dot sights with different plates you can swap out.
