Meet the Chiappa M6 X-Caliber 12 gauge survival shotgun, the only survival rifle you’ll ever need. It’s not quite as compact as the Henry AR7, but it’s pretty close and the versatility of the M6 far outshines the competition. The rifle was originally designed to fire a 12 gauge shell and a .22lr, but with the X-Caliber adapter set the M6 can fire up to 12 different calibers including .380 , 9 mm , .357Mag/.38SP , .40 S & W, .44 Mag, .45 ACP , .410/.45colt, and 20 gauge. The entire system is made of steel except for a foam insert in the butt stock to reduce weight. By pressing a single lever, the M6 can be folded at a hinge point to a compact 18″ that can easily fit in most backpacks. It features and optical fiber front sight with an adjustable rear sight. There’s plenty of rails for any scopes, lights, or bipods that can be attached at your convenience. With an MSRP under $800 you can’t beat this apocalypse gun.
