The Fostech Origin 12 is an AK-derived shotgun chambered in 12 gauge. Although similar to the Saiga shotguns, it must be noted that it uses different components designed from the ground up.
Primarily developed for use in civilian shooting sports (such as IPSC or 3-Gun), it has gained a reputation for being the fastest-firing semi-automatic shotgun.
- The Origin 12 has made an appearance in Tom Clancy's Rainbow Six: Siege. It was renamed as the FO-12 shotgun, most likely done to avoid copyright. It is used by the Polish CTU in-game.
