Anti-gun politicians already trying to take advantage:
NJ Senator saying "this is why NJ bans assault weapons. NV should do the same". This idiot doesn't know full auto is already illegal, unless you're a tourist type gun range.
Hillary saying this is why the NRA should not allow "silencers". Again idiot doesn't know suppressors already legal in NV, so if he wanted to, the shooter could have used one.
It's not illegal, but it is tightly regulated and limited. Import and manufacture of full-auto "machine guns" for the public market is prohibited.
1) You need to be eligible to possess firearms in general.
2) You must live in a state where NFA items are permitted and machine guns, specifically, are legal to possess. (about 40 states)
3) The machine gun you wish to acquire must have been manufactured on or before May 19, 1986.
The first and only full-auto I've ever used was in Nevada.
That being the case, new guns have been manufactured to not accept/operate with full-auto trigger parts, to prevent ease of modification of semi-autos to full-auto.
Existing machine guns are held mostly by collectors. The prices are extremely high, so the average gun buyer can't afford the prices, and the supply of available machine guns for sale is very small in number. Getting your hands on one in a state where it's legal takes time, money, and extra ATF scrutiny.
