So, if you're on FB check out Military Arms Channel. There is a recent video of an AR pistol sporting the Dolos quick barrel change system and the Law Tactical Folding AR Stock Adapter. Makes this pistol very compact for travel. If you're not on FB, just google Dolos and Law Tactical. I'm thinking that I'd want one to pack in a backpack instead of an AR-7. Especially since we live in the NW, where actual predatory animals still roam the woods. Anyone see either of these systems in person? What do you guys think?
