We ought to be able to build an NFA firearm right now, especially if we pass all the background checks. If we can legally buy a full auto for $5000 and up, then why can't we legally build one for $500?
Considering that the BATFE is a FEDERAL agency and the FEDERAL Constitution say quite clearly "shall not be infringed", you'd think the BATFE could just go F*CK OFF!!! And take their unConstitutional '34 NFA, '68 GCA, and the POS Brady Bill with them....
