“Do the full auto rules still aplly?”
That depends on where you live. There are conflicting court decisions.
NFA rules apply. All you’re doing by working the receiver is just making a non-transferable firearm that the gov’t doesn’t know anything about.
It looks like this is a classic case of gov’t over-reach after this- http://www.guns.com/2014/02/27/california-gun-parts-maker-assault-city-sign/
The city complains about their signage and suddenly the ATF shows up days later demanding things? Welcome to Obama’s America.
