Kevin, Optional as in you can tie stuff directly to the frame without using it? How do the bags attach to the pack without this talon? Any pics in that config?
Looks like you could stuff the butt of the rifle in the water bottle pocket, cinch the straps around the stock and have a nice, secure way to pack a rifle over long distances. A simple, secure way to carry a rifle (doesn't have to be quick access, but it can't be falling out when alder bashing) is a big deal to me.
