Well, cluster, step right in to my office!
First, you never, ever say that the reason that you want to incorporate is to obtain NFA weapons. Never. Ever.
It's against the law! Or at least the ATF's present interpretation of the law. Sort of like obtaining an FFL simply to collect guns, or to sell guns only at gun shows!
The reason that you want to incorporate is to continue an ongoing business as a corporation, or to start an investment business.
One of the investments that your new company may decide to invest in is NFA weapons. Can you imagine just what a return on investment your company might have been able to realize if it had bought Colt M-16s back in the late 80s when they were going for $1500.00 to $1700.00 each.
They sell for $6,500.00 to $8,500.00 now.
And they're not making any more of them, at least for civilian consumption, so you can just imagine where prices are going to go over the next several years.
I am a corporation and I've never bothered to invest in any NFA stuff, other than maybe a suppressed .22 Ruger pistol or two.[:D]
