A semiautomatic shotgun that has at least two of the following:
i. a folding or telescoping stock;
ii. a pistol grip that protrudes conspicuously beneath the action of the weapon;
iii. a fixed magazine capacity in excess of five rounds; and
iv. an ability to accept a detachable magazine.
Per new law they got rid of the 5 round rule so you can have a pistol grip.
I cannot find a link of the latest assault weapon definition.
