Okay, every guest gets help, and every guest is safe.
So, what's the problem? The problem is, in the media's eyes, is Americans getting used to the idea that they, the non-Only-Ones, can fire militia weapons, which is the exact wording from US v. Miller 1934, which says we have a right to militia weapons, which includes machine guns.
After firing a machine gun, some of them will want to buy one.
Pretty soon, Americans start wondering why nothing after May 1986 is available for them to buy (say, like, a Glock 18 or an H&K MP7). Pretty soon, idiocy like the Hughes Amendment gets overturned, and the whole 1934 NFA registry comes under attack. Maybe, the NFA gets overturned.
All because of businesses like this. No wonder the media hate them; they are spreading ideas of freedom. Can't have that.
If they have a Class III license, $20,000 for the automatic, and the money to feed it, as well as the $200 for the tax stamp.
