I think that the whole "offlist" lower thing is the sacred cow of the CA. AR enthusiast crowd.
I also think that calguns has been something of a Mecca for the offlist lower movement and that's a good thing. The problem is that it has no doubt come to the attention of those at DOJ responsible for formulating some type of policy for these lowers. This is wild speculation, but if I were a power at calguns I would try to keep as much of the hysteria or topic driven "what can we do to save the children!", or "They shall not infringe my right to have an assault weapon" type threads all over the board (a'la the article) to a reasonable minimum.
That said, I guarantee you that DOJ already has a strategy/policy for dealing with these and no amount of good, or bad, publicity is going to change that. The only questions are when will they officially declare that policy and what form it will take.
I think I'll probably go get a lower just for the hell of it. At worst I'll lose some bucks on the EE later on (who hasn't!?). At best, I'll end up with another registered AR (I'm thinking a middy).
ETA: That F**king idiot in the article really should have stopped to think that some kooky looking asshole with a che guevara red face mask cradling a big mean child killer doesn't do much for the CA. gun owner. Talk about making yourself a tool of the enemy.
