FFL License requirements: Destructive, and non-destructive. Whats the definition?

[PraiseCaster]

I'm curious as to the definitions under the FFL requirements as to what is "Destructive" and "Non-destructive".

Is destructive referring to the manufacture of ammo, and non-destructive the manufacture of guns?

[yellowfin]

Destructive Device means stuff like mortars, howitzers, etc. and explosive ammunition for them. It's the weird 6th NFA category that also includes Striker 12's/Street Sweepers.

I’ve always operated under the “if it explodes its an DD” principle. Granted there are other items considered DDs.

So say I want to apply for an FFL license and build AR-15's, that would be a non-destructive. Correct?

Oh, and thank you gentlemen, for your response to my query.

Sounds like what you're looking for is just a type 07 FFL, which would classify you as a manufacturer of Title 1 firearms, which doesn't include anything "destructive".
