Yes, Virginia- we have machine guns! Virginia State law does not ban ownership of full autos by private citizens, so long as Federal law is followed. It DOES require that all full autos, short barreled shotguns, etc be registered with the Virginia State Police. There are several Class III dealers here in my home state of Virginia, and several folks that shoot full autos at my range each week. Expensive, though.
Additionally, a lot of it may depend on the politics of your County Sheriff, who gets to have a say in whether or not NFA permits are approved. In some states, an NFA living trust can be established, which circumvents the County Sheriff, but you would need to check your state legislation or contact an attorney in that field to see if that is possible.
The only other ways to go about doing this would be to get an FFL 01 dealer's license, and additional NFA licensing, which would allow you not only to purchase transferrable full auto weapons, but would also permit you to purchase non-transferrable (post-86) dealer samples, which you could rent out for range use, but would not be able to sell or transfer to a private citizen. Additionally, you could obtain a Class III manufacturer's license, although, again, nothing you manufactured would be transferrable to any private citizen.
You can't unless your have a license to buy or sell automatic weapons T.T
18 for a military style semi automatic. For a true assault rifle, which would be an NFA Class III full auto weapon, 21.

You can. It is not against the law to own fully automatic weapons provided you follow all the rules. 21, clean criminal record, money to buy, CLEO signature, etc..
you get the weapons from quests or you buy them
You need to finish the game, then upgrade your weapons to full and buy it from the Bonus Features.
In a way the M16 is a machine gun, but it can also do three round burst and semi automatic. civilians are not allowed to have automatic m16s unless you have an automatic weapons permit, but you can have a semi automatic M16. (an AR-15 is almost like an M16 and much cheaper if you're looking to buy one.)
No, It is Semi automatic mechanical. You can buy and electric trigger that allows for full auto.
you cannot buy it as an automatic, but you can pay to have it changed to an automatic

If you buy a standard then it will be a manual transmission. If you buy an automatic, then it will be automatic.
