i just got my forms to fill out, so the list may not be complete yet.... i didnt see any listed as 0 accross the board... i hope to see my name on that list next year.
Hmmm, interesting that Knight's Armament, under both FFL's combined, only produced 267 rifle and no other firearms; 24 of the rifles were exported.
Regarding the "misc firearms" my first thought was that would probably be NFA type arms like suppressors, AOWs, DDs, but I didn't see any of the big suppressor manufacturers on that list so I'm not sure what that is.
ETA, upon further review, seeing that Cav Arms, Bushmaster, Mega Machine Shop (all three make AR receivers), Nodak Spud (AK receivers), and Stiller (Precision Rifle actions) etc. are listed, I think "bare receivers" would be the culprit for all the "misc firearms". A receiver is neither a shotgun, rifle, pistol, or revolver so it would be misc. until it is built.
