VIKING ARMS SOS-12
This shotgun is primarily known for its unorthodox appearance, said by some to be a combination of AR15 and SPAS-12. Viking says that it does have some utility as a sporting gun, it was designed primarily for use by civilians in home defense. It is thus easy to care for, uses one of the larger-sized magazines in a short-barreled shotgun, and tries to strike a balance between enough weight to keep barrel climb down and not being too heavy for the average out-of-shape homeowner. The barrel is equally-suited to firing shot, slugs, rubber rounds, batons, or even exotic loads such as rock salt! The biggest defect in the design is that one normally needs a gunsmith to adjust the sights; the Viking is not meant to go out of the dealer s building without some sort of training for the buyer, and adjusting the sights is supposed to be part of this process. The shape of the stock is more meant to be trapped under the arm and the weapon fired from the hip than for the weapon to be aimed, and many users found that the Viking does not shoulder very well. As gun ownership laws in Great Britain could be a bit draconian, there was more export than domestic sales of the Viking.
