AK47

The AK-47 is simple assault rifle, inexpensive to manufacture and easy to clean and maintain. Its ruggedness and reliability are legendary. The large gas piston, generous clearances between moving parts, and tapered cartridge case design allow the gun to endure large amounts of foreign matter and fouling without failing to cycle. This reliability comes at the cost of accuracy, as the looser tolerances do not allow the precision and consistency that are required of more accurate firearms. It is chambered for 7.62x39mm rounds and uses 30 round magazines. AK47 is a Fallout Tactics weapon.
 * In-game Description: The AK47 and its derivatives formed the mainstay of Soviet Armies. Its reliability, ruggedness, and accuracy have earned it the reputation of being the best assault rifle ever made.
