OTs-12 Tiss (Yew Tree) (Russian:ОЦ-12 Тисс) is a Russian fully automatic assault rifle chambered for the sub-sonic 9 x 39 mm round. Work on the weapon started in the early 1990s. Basically a rechambering and reworking of the more conventional AKS-74U assault carbine it differs only in the bolt barrel muzzle-brake and magazine. The 20-round box magazine was designed so it could be compatible with standard current-issue ammo pouches but a larger 25-round magazine was rumored.
