Guess I should update after all the slingmount talk, tried a few different methods and currently have a make do setup.
I didn't even try the ring dealio, it was mostly a joke, but tempting to try. In the end I was concerned with possible wear of the tube due to the steel ring moving against it.
Picked up a KNS sling stud mount for a regular AR handguard, but the diameter of the flanges that come with it are the same as the diameter of the holes in the guard, so it was a no go.
Ended up just throwing a short section of rail on there with an MI sling mount for an HK hook. I looked more at the DD mount that would go on the top rail in a horizontal fashion, but was concerned with wear since the HK hook would be going through a swivel mount. I may try it out at a later date since the current setup looks like a hodgepodge of crap and definatly is not as light as possible. For the time being, it'll do.
