I took the approach of any legislation being modelled after CA, Chi., etc. laws, and figured the cheap mags and cheap ARs of 2018/2019 was good and affordable insurance. Should've tossed another grand or two towards ammo too, but I've got enough for a while. Those Global Ordnance AR steel mags for $5-7 are a freaking steal for JIC use...no reason why someone couldn't drop $100 and grab a dozen (or more, on a hot sale).
