Thanks for the response! Virtually any semi-automatic firearm, hand-gun or rifle, and be converted fairly easily to full auto by, for example, filing down the "sear" part which holds back the hammer after it is cocked. If the sear does not hold back the hammer, it will fall immediately on the next live round, as long as the finger depresses the trigger. I'm not a gunsmith, but I know "sear filing" is one conversion approach.
Here's what happens to you the moment you convert an otherwise legally owned firearm to full auto capability: You have committed a federal felony, which will land you in prison for 5 or more years. Of course, you lose any firearms you own, without any compensation, and bear the "felony" stigma for MANY years.
