I'll a fresh cup of coffee the DoJ waffles or says "No" to any question about the legality of any specific make or model. They tend to err on the side of not telling you something is legal when they aren't sure. Any answer you get from them will be equivocal at best.
The Legislature has now tried twice and failed to ban what they really want to ban, which is scary looking guns. The DoJ people aren't stupid. They understand the Legislature's intent and they understand the SCOCR decision. They know damn well it's now legal for people to buy certain items, but they're caught in the middle and really CAN'T tell you it's OK to do something they know the Legislature doesn't want you doing.
The provisional state government of the Occupied California Republic has put itself in an endless loop, an unwinnable game of catch-up with gun manufacturers. Right now the only way they can stop people from legally acquiring complete, functional ARs is to STOP listing new models.
