1.Will a 30 rd Mag Pul magazine work in a Calif legal AR15.
2.Can someone in Calif possess a 30 Ar15 Magazine.

1. Are you asking whether a 30 round, Magpul magazine will function properly in a off-list lower receiver equipped with a Bullet Button?
If the rifle is not a registered assault weapon, it is a felony to put a 30 round magazine in the mag well.
If the BB-equipped, OLL is taken to AZ, the Magpul can be used and should function properly (magazine variability being what it is).
2. Yes, Californians are legally allowed to own and use 30 round magazines. There are certain conditions which must be met but it is legal if those are met. An example would be a Californian who owned/possessed the high cap magazine before the cutoff date (1/1/2000) and uses it in their registered assault weapon.
