I wouldn't bother with full auto. I have seen one shot on semi auto pretty damn fast. I will get a website for you tomorrow where you can buy some pretty cool and cheap imported military rifles. I have two buddies that just bought some sort of 7.62x39 bolt action rifle with 800 rounds for around $100 each. The gun itself was $40. They have shot atleast 400 rounds each with no problems. They are also fairly accurate.
