TK509: Russia’s futuristic new gun How the US AR-15 rifle was reborn in Russia.
The TK509 is a semi-automatic pistol with blowback. The weapon is marketed as smoothbore due to the new .345 TK cartridge and 305-mm Paradox-style barrel (i.e. it has a section with grooves to stabilize the bullet and twist it during flight).
It is made by Molot Arms and Tekhkrim from Vyatskiye Polyany (800 km east of Moscow). The former produces aircraft-grade aluminum barrels for .345 TK cartridges; the latter assembles the weapon and applies chrome plating and a protective, decorative coating.
According to Vadim Kozyulin, professor at the Russian Academy of Military Sciences, the TK509 is the ideological continuation and development of the US AR-15 platform the main competitor of the AK in the small arms market.
