Not really. If you got the time and money (big money), you too can have a full auto weapon. Of course subject to local laws. I know in FL and NV and several other states, it’s perfectly legal to own a full auto weapon. Just hoop jumping and big bucks required.
-knowing where they had been put exactly , I got to pop a couple of them with a Jap 7.7 mm LMG with which you could squeeze off single shots .BTW, the gun had been converted to fire 7.62x39mm ammo with a conversion kit made near Wickenburg--also used AK-47 mags---
