Designed during the height of the Cold War by the Soviet military, the APS (special underwater assault rifle)was intended for use by commie spetznaz and combat diver teams to stealthily kill Yankee bastards and their capitalist stooges.
As first brought to us by The Firearms Blog, the APS shoots 5.6mm darts using a standard gunpowder charge in a sealed cartridge. The weapon can be fired above and below water, but specs show significant degrading of the weapon when not fired submerged.
The magazine holds 26 rounds and the whole getup weighs 7.5 pounds loaded.
