Oh yes. I once had a fully automatic M16. It worked very well. Lasted me a good amount of years. You can go to EBay.com and search up "fully automatic guns" Now, things you might want to consider. -FPS: FPS if you don't already know is "feet per second", this is how you know how fast the gun shoots. Higher FPS means farther range and it's hurts more :D -metal: full metal automatics are usually downright the best. Plastic ones are cheap but still good. Metal ones tend to be expensive but last a good amount of time and still works great afterwards.

Selective fire, single shot or six round bursts. They don't do full auto because a high rate of fire will make a CO2 gun freeze up. I want one too, to harass the neighborhood cats.
