The only full auto weapons I have fired are, a Thompson w/50 round drum, an Uzi, and a 10 inch barrel AR-15 w/red dot sight. The Thompson was fun and I could picture a gangster with one against police with .38 revolvers, and what a terrorizing weapon it was in its day. I always thought UZI's were a piece of **** but this one actually had a nice trigger and would be very effective out to 75 yards or so and I liked it more than I thought I would. The AR-15 was made by a friend who custom fabricated a compensator for it and it had virtually no recoil or muzzle climb. It was small and light weight but easily able to keep bursts on man size targets out to 150 yards. It was far superior to the other machine guns.
