you can't just put that on a fixed stock rifle in a compliance state without extra work as they are pinned.

the point of the post is that this is a dedicated single point sling mount for use on the 15-22 without removing the stock, and so far its the only one i've seen.

that mount, the shipping, and the cost of having a gunsmith install it could be equivalent or more (i was quoted $50 to drill pin, and replace it. same as stock change), and not easily removable without returning to the gunsmith.
