Changes

In 1993, a few hundred OTs-12 carbines were built and delivered to the Russian Internal Troops for evaluation. The weapon trial was less a demonstration of the OTs-12 itself, but rather a demonstration of the 9x39mm cartridge, and its effectiveness in close-quarter urban combat compared to the standard 5.45x39mm M74 ammo. OTs-12 production would be cancelled later that year due to a lack of interest in the weapon itself, though it performed excellently during the trial and was cheaper to produce than the more specialized AS VALVal. At the time of the OTs-12's debut, there were just too many other weapons using the 9×39mm caliber round, such as 9A-91 and SR-3 Vikhr. These weapons were more compact and weighed less than a default AKS-74U chassis, and performed just as well. With the 'Tiss' project abandoned, TsKIB COO started to work on the OTs-12's successor: the OTs-14 'Groza'.<ref name = "Tiss Wiki">[[wikipedia:OTs-12 Tiss|Wikipedia entry on OTs-12]]</ref>
