Rob,
As we all know,the gov't is not happy w/o loads and loads of paperwork.

Believe it or not,in my state at least,it is easier to get a class 3 item and less paperwork than a standard firearm. Basically one form and that's it.

One of the guys at the range had his tax stamp in three days.

I fired some M-2s while in 'Nam and found that I liked semi-auto better. Full auto in any configuration is basically a waste of ammo. At least in my opinion.
