Welcome to the club.
California has had a "Assault Weapons" ban for a few decades now, and guess what, the number one selling long gun in the state is the AR-15. I have two myself.
You just need to pay for accessories to make it featureless, which funny enough makes them look even more aggressive then stock, but hey, it makes them safer somehow right clueless government???
Stupid requirements on barrel size, even a pistol or vertical grip on specific types of rifles, because of how they look, sad to see it spreading around. But as mentioned, spending more money by the law abiding owner "fixes it", interesting how that works.
