Design

The USAS-12 is a gas-operated, selective fire weapon, designed to provide sustained firepower in close-combat scenarios. It accepts detachable 10-round box magazines or 20-round drum magazines.[1] Both types of magazine are made of polymer, and drum magazines have their rear side made from translucent polymer for quick determination of the number of shot shells left. It has an effective range of 40 m. In the early 1990s, a new CQ model of the USAS-12 was created. It looks similar to the original model, but unlike the original, it lacks the front sight and has a re-modeled carry handle.

History

The history of the USAS-12 dates from the 1980s vintage designs of Maxwell Atchisson. In about 1989, Gilbert Equipment Co. (USA) decided to bring up the selective fired weapon, broadly based on principles employed in Atchisson shotguns. The design of the new weapon was produced by John Trevor, Jr. Since Gilbert Equipment Co. had no manufacturing capabilities, it started to look for possible manufacturers. It turned out that the only maker that agreed to produce this weapon was the South Korean company Daewoo Precision Industries, a part of the high-tech Daewoo conglomerate. Daewoo engineers adapted the new weapon to their manufacturing techniques, and mass production commenced in the early 1990s. The USAS-12 sold well to military and security forces of several (unspecified) countries in Asia, and more than 30,000 of USAS-12 shotguns were made by mid-1990s.[2]

During the same timeframe, Gilbert Equipment Co. tried to bring a semi-automatic version of the USAS-12 to the U.S. market, but Treasury Secretary Lloyd Bentsen classified this firearm as "having no sporting purpose", so it became a "destructive device" under the U.S. National Firearms Act of 1934.[3] This greatly restricted its civilian use. During the late 1990s, RAMO Defence Co. began to assemble USAS-12 shotguns from Korean and U.S.-made parts for sale on the domestic market, but sales of this weapon were limited to government agencies only.[2] Today, this shotgun is still being manufactured by S&T Daewoo in Korea for military and law enforcement sales only.

A U.S. firearms manufacturer, Ameetec Arms LLC of Scottsdale, Arizona, started the manufacture of a USAS-12 semi-automatic clone in 2007, called the WM-12; it mainly differs from the USAS-12 by the lack of fixed sights and carrying handle, replaced by a Picatinny rail. The manufacturer stated that the WM-12 is not a "destructive device", and would thus be readily available to civilians.[4] As of January 2008, however, the WM-12 was no longer to be found on Ameetec Arms online catalogs, because it was discontinued after its pre-production run. Only a few WM-12s were built using USAS-12 demilitarized shotguns.

gollark: Personally I consider rounding and shading very uncool.
gollark: Yes, why?
gollark: I maybe can (although likely not *now* given the situation), but it would be annoying and expensive. Also I have no idea where or how to.
gollark: My Wileyfox Swift 1 was pretty great, it had a plastic back cover, dual SIM cards, and a removable battery, but a design flaw in the micro-USB port apparently made most of the existing devices become unusable after about two years.
gollark: Especially on the everything-is-glued phones.
