Bottom line--buy whichever you want.
Is there a current frenzy of panic buying--obvious answer is YES.
Is the panic buying justified?? NOBODY KNOWS!!!!! that's the long and short of it. Lots of opinions on both sides of the issue--but they are just that--opinions. Two of the top-tier makers (LaRue and Lewis Machine) are taking orders, but they are over a year and a half out from delivery.
Will all this blow over? Nobody Knows! Will the republicans bow to media pressure on an AWB? Nobody knows! Will the Prez take some Executive Action that (at least temporarily) bypasses Congress?? Nobody knows!!
Bottom line--if you wait--you may or may not be able to buy one. So, if you can find one--buy it NOW just in case.
