X-Caliber Survival Shotgun – One Gun, 12 Calibers says in their video demonstration, the X-Caliber is “The Ultimate Survival Shotgun. One gun; 12 different calibers. Find it. Fire it.” The concept is truly impressive. Notice how all of the caliber adaptors are carried in the stock. This demo fires all calibers at 50-70 feet. Many question the accuracy of this firearm due to its engineering. What do you think? Is the accuracy in this video good enough for a survival shotgun?
