Good point on the stock holes being for the pins. It was when I put a pin in there that I thought "why not try an ambi loop?"
The sling works well for me in that position. At the receiver sling location, the rifle was a little high against my body (without having the sling loose). In this location, both the rifle and sling sit right where I want. It's nice to have some alternative locations and be able to easily find a spot that works best.
If you look at my old stock, you can see where my sling connected in a very similar position (but not as cleanly integrated).
