Les, I also like that folding stock set-up. It would definitely allow a wider range of stealth carry methods.
A few weekends ago we took our camper over to a nearby state park for a two day outing. I found a backpack for $30 at wallymart that was just long enough to accommodate my AR pistol, four loaded mags, and two days change of clothes. Backpacks have become a common thing (I see folks carrying them everywhere) so having the back-up firepower basically hidden in plain sight was a comfort.
I did not shoulder carry it everywhere, just kept it either in the camper at night or in the vehicle by day as a back-up to my sidearm.
