"A destructive device (DD) can be two basic categories of things.
It can be an explosive, incendiary or poison gas weapon, like a
bomb or grenade. It can also be a firearm with a bore over 1/2",
with exceptions for sporting shotguns, among other things (see
discussion below). I call the second category large bore
destructive devices. As a general rule only this second category
is commercially available."

Whoomp, there it is.

Even Better...
"26 U.S.C. sec. 5845(f) "The term destructive device
means
1) any explosive, incendiary or poison gas
A) bomb
B) grenade
C) rocket having propellant charge of more than four
ounces
D) missile having an explosive or incendiary charge of
more than one-quarter ounce
E) mine, or
F) similar device
2) any type of weapon by whatever name known which will, or
may be readily converted to, expel a projectile by the
action of a explosive or other propellant, the barrel or
barrels of which have a bore of more than one-half inch in
diameter, except a shotgun or shotgun shell which the
Secretary or his delegate finds is generally recognized as
particularly suitable for sporting purposes;"

Little late to post, but I checked and found out that 50 cal was the limit excluding shotguns. (concerning the standard sale.)

I had known that to be true but the site that listed that siminov gun threw me off, "cant believe everything you read."

Whoomp you were right.... lol

fifty should do anyways.
