I've taken four AK rifle classes using a Sneaky Bag slung over the shoulder without the waist and thigh straps attached. For me, it works great. I can move the bag around behind and get it out of the way, let it hang at the side and easily draw magazines or put empties in the dump pouch, or I can swing it around front when I go prone and use it as a rest. I see no reason for just a regular guy to not take a class with such a set up. However for the Civilian guerrilla, insurgent, tactical, operator something like the Attack Rack is probably desirable.
Another advantage of the simple bag, around the home, or in a vehicle, it's a grab and go thing, no need to get suited-up.
