Home boy that was giving you instructions was walking around with a felony:

Senate Bill (SB) 23 Assault Weapon Characteristics A semiautomatic pistol that has the capacity to accept a detachable magazine and any one of the following: A threaded barrel, capable of accepting a flash suppressor, forward handgrip, or silencer. (B) A second handgrip. A shroud that is attached to, or partially or completely encircles, the barrel that allows the bearer to fire the weapon without burning his or her hand, except a slide that encloses the barrel. The capacity to accept a detachable magazine at some location outside of the pistol grip.

Definitely don't take advice from that guy anymore.
