Fires the subsonic 5.45x39mm cartridge that originated from the USSR. This weapon is great as the ammunition is somewhat common at military spawns and features a Kobra red dot sight and a suppressor. Due to the smaller round this gun fires it does not pack much punch. However during the night, if utilized properly could be used to great efficiency as the suppressor quiets the noise and eliminates muzzleflash making the shooter very hard to find(especially when you targets fo not have night vision).
