Ventura County checking in. I am not the final authority on this but I'd go so far as to say Orange and Ventura are some of the more conservative counties in CA. If you were to say LA or SF, I'd say you are screwed.
+1 for the Thorsden stock; of all the featureless options, it's the one that best resembles a rifle I'd want to use but there seemed to be extra distance to reach for the trigger. Other than that, you just need either a muzzle brake or thread protector, and an Overall Length of over 26" . Now you got something looking more like a Ruger Mini14.
Oh, and get good at reloading. After July 1st, ammo purchases require a background check.
