The M6 from Chiappa Firearms is the newest survival gun to hit the market. This gun features a 20 gauge shotgun barrel over a .22 long rifle barrel. It folds in half to a compact length of 18.5 inches by pulling down on the trigger guard. The folding feature allows this gun to fit into tight spaces or slip into a backpack making it a perfect survival weapon. The folding feature also allows for a quick and easy cleaning without having to disassemble the gun. The picatinny rail system gives you the option to add optics or lighting. The skeletonized butt is filled with a super tough foam that reduces recoil of the gun and provides a place to store extra ammunition.
