POTD: A Fully Automatic Shotgun – The Legendary USAS-12
Sam.S 08.16.23

Welcome to today’s Photo of the Day! Here we have a Call of Duty gun if there ever was one. The peculiar USAS-12 shotgun originated from 1980s designs by American Maxwell Atchisson. In 1989, Gilbert Equipment decided to produce a selective-fire shotgun based on Atchisson’s work. They enlisted South Korean company Daewoo Precision Industries to manufacture the USAS-12. Mass-produced through the 1990s, the USAS-12 was sold internationally to military and police forces. Around the same time, Gilbert unsuccessfully tried bringing a semi-auto version to the U.S. civilian market. The original USAS-12 remains available only for military/law enforcement overseas from Daewoo, while some semi-auto clones have been produced in small batches for government agencies.
“Originally developed in the 1980s, the USAS-12 takes many design cues from Maxwell Atchisson’s 1970s vintage Atchisson Assault Shotgun, being a gas-operated magazine fed shotgun patterned after the M-16/AR-15 family of rifles, in particular arranging the firearm to put the barrel as close in line with the shoulder as possible to diminish felt recoil. First conceived as a military weapon, Gilbert Equipment teamed up with Daewoo Precision Industries of South Korea to produce the USA-12 as a full automatic shotgun for government contract sales, later formulating a semi-automatic model for the North American commercial market. Arriving on American shores in the late 80s and early 90s, the semi-auto UAS-12 soon ran face first into the Bureau of Alcohol, Tobacco, Firearms & Explosives, who used the wording of the National Firearms Act to have the shotgun (along with the cylinder-fed Armsel Striker-12, aka the Street Sweeper) declared a Destructive Device; while shotguns are traditionally given a pass on having a bore greater than a half-inch, this only legally applies to items “generally recognized as particularly suitable for sporting purposes”, with said recognition more or less entirely hinging on the ATF’s opinion on the matter.”
