"Assault firearms" means:
1. Any of the following firearms:
...
Avtomat Kalashnikov type semi-automatic firearms
...
2. Any firearm manufactured under any designation, which is substantially identical to any of the
firearms listed in paragraph 1 above. As used in this definition, the term "substantial" means
pertaining to the substance, matter, material or essence of a thing and the term "identical" means
exactly the same. Hence, a firearm is substantially identical to another only if it is identical in all
material, essential respects. A firearm is not substantially identical to a listed assault firearm unless
it is identical except for differences that do not alter the essential nature of the firearm.
The following are examples of manufacturer changes that do not alter the essential nature of the
firearm: the name or designation of the firearm; the color of the firearm; the material used to make
the barrel or stock of the firearm; the material used to make a pistol grip; and a modification of a
pistol grip. This is not an exclusive list. A semi-automatic firearm should be considered to be
"substantially identical," that is, identical in all material respects, to a named assault weapon if it
meets the below listed criteria:
i. A semi-automatic rifle that has the ability to accept a detachable magazine and has at least
two of the following:
(1) A folding or telescoping stock;
(2) A pistol grip that protrudes conspicuously beneath the action of the weapon;
(3) A bayonet mount;
(4) A flash suppressor or threaded barrel designed to accommodate a flash
suppressor; and
(5) A grenade launcher;
