I knew right away that Hello Kitty AR would be posted.
That's a CA legal AR15, you can't have a pistol grip and a detachable magazine on the same weapon, and that mag while it looks real is actually pinned at 10 rounds. Other ARs in CA have a pistol grip but the magazine has to be permanently fixed to the rifle or require a tool to remove it, that way you either need a screwdriver or you have to separate the upper and lower every time you reload.
