Get a Class III permit pay $ 200.00 transfer tax, and you get a fully automatic gun, if you buy a 50 Caliber Machine gun, contact Mike Dillon, at Dillon and get a progressive reloader, with 50 caliber dies, as you will be spending all of your time in the basement reloading ammo.
Montana has a Auto Weapon get together each year, and the noise is outstanding. Those old 50 Calibers still demand a lot of attention.
You replied to the wrong person my friend.
