Armory USA receivers are cut for the double-hook FCG, so you can use either single- or double-hook innards. I went with the double-hook myself-- after looking at them in my Chinese guns for almost twenty years, it just
looks like AK parts.
Yes: Type-2, one mm, 7.62 caliber. Do yourself a favor and get (at least) one of the grip reinforcement plates sold by Ohio Rapid Fire (and others)-- it will make your grip feel much more solid and make your lower last longer, but they have to be spot-welded in. (

Compliance: I'm going receiver, FCG, gas piston, and a muzzle device from the guy TravisAasen told us all about (thanks, Trav, we all owe you a beer-- I'm working on a way to send it via the Internet)! Now to save up the money for a press and a Plinker's jig-- oh yeah, and order more kits--
--and don't forget the GunKote or Norrell's-- Brownell has both.
One more thing: if you use an Armory or other stock-AK receiver, you'll need a regular safety, because the original Tantal safety rides too low. Global Trades happens to have some Polish safeties that fit the bill-- symmetry, no?
