How could I legally own "destructive devices"?

So let’s say that I’m tired of shooting those wimpy .50 cal rifles, and decide I need a Lahti 20mm rifle/cannon just in case I run across Hogzilla. And a M203 grenade launcher. And mebbe’ a coupla RPGs. Let’s say I have a completely clean background, and money is no object. If I was willing and able to do what it took to get the required license/ certification/ permits, how could I own military-grade weaponry?

I believe you’d need to start first with getting a Class III weapons license.

More on classes and types here:

The Lahti would be fairly simple. Class 3 registration and fees.

Explosives really complicate things.

Reams and reams of paperwork.

Minnesota.

Most states have similar guidelines and policies.

ETA: The simpler solution would be to buy some property in a less restrictive country and enjoy your weekends there.

Note also that the 203 counts as a destructive devices as well as each round of ammunition. Good thing money is no object as the tax stamp is $200 per.

FWIW,

Personally, I’d think it rather odd for a person to try to become a dealer or manufacturer of NFA weapons if they had neither owned one, nor been a regular FFL holder.

You don’t get a license just to own NFA weapons, you apply for permission for each one you buy.

The best thing to do, at least for your first one, is to find a local dealer who will order whatever you want for you, and help you with the paperwork if necessary.
