It works as described. - Arisaka Defense Offset Optic Plates

To the other reviewer that gave one star, you're an idiot. You reviewed, and gave a one star review for a product you didn't use, because you didn't like the farken description? If you researched the product AT ALL, you'd see it's a system that requires the rail mount, too. And allows the user to swap out different optics simply by replacing the proprietary mounts.

I have the RMR mount, it's solid and machined well. Go on Arisaka's website if you want to see the versatility of it. Everything IS cheaper here, though.
