TOZ

TOZ is the Russian abbreviation associated with Tulsky Oruzheiny Zavod, the Tula Arms Plant in Tula, Russia. The plant traces its state arms-factory origin to Peter I's 1712 decree, became a long-running center for Russian and Soviet small-arms manufacture, and is now described in public sources as part of the High Precision Systems holding within Rostec.

The Tula plant's public history spans imperial, Soviet, and post-Soviet production. Rostec describes it as Russia's oldest defense enterprise and links its output to Mosin rifles, Maxim machine guns, TT pistols, Kalashnikov-family production, the GP-25 Kostyor grenade launcher, and Konkurs anti-tank guided-missile work. That range makes TOZ useful context for infantry weapons whose source material uses the factory abbreviation rather than a longer legal name.

Current public descriptions place the factory at Sovetskaya Street in Tula and identify JSC Tula Arms Plant as a High Precision Systems / Rostec enterprise. The TOZ abbreviation appears in producer references for GP-series launchers and should be read as manufacturer context, not as evidence of any specific battlefield use.
