I'm turning 18 in 8 months, will I still be able to buy a gun (AR-15/870) in California, or America for that matter? Alaska is looking good right about now. Or Mexico. I can at least use it there. Also, a consistent observation of a trend on the forum is: new ar my new gun is this legal????? AR-15 shotgun problem Notice I mentioned the entire subject in the title. AR-15 Legality in California. The object, the problem, the place.
