Ahhh, American ingenuity. - The Ultimate Survival Weapon Shooting every caliber bullet between .22 to .308 The weapon of choice, one gun to replace them all! "If someone has a gun and is trying to kill you, it would be reasonable to shoot back with your own gun" ---The Dalai Lama  The Scavenger 6 is a new rifle that looks like a revolver and can fire 21 different calibers of ammunition, just by swapping out the cylinder. In a post-apocalyptic scenario where survival is dependent upon scavenging resources, it pays to be prepared. That’s the thinking behind Scavenger 6, a new rifle that can fire 21 different calibers of ammunition. Though rifle hardly seems a fitting term. It looks like a cross between a .44 Magnum and an M1A1 carbine, and the crazy thing is that’s not inaccurate. Scavenger 6 was designed and created by Air Force veteran Tim Ralston, who rose to prominence as an inventor and survivalist after appearing on the National Geographic Channel’s “Doomsday Preppers,” a reality television show about post-apocalyptic scenarios and survival planning. https://scavenger6.com/
