I have a quick question which probably won't be quick but here goes.  How many Us made parts do I need for my AK-74 build to make it US legal.  Thanks a lot I'm very confused on how many parts I've heard 5 and 14 so I'm not sure I need to know before I get it built.  Thanks again.

six
reciever=1
fcg=3
piston=1
us grip or muzzle brake=1

Thanks alot I have a US pistol grip, Gas psiton, Reciever and I'm getting the Red Star Arms Two stage trigger so that should be enough.  I can't wait to get mine built.

The 16 countable parts in a AK with a muzzle device, no more than 10 of which can be foreign made.

(1) Receiver
(2) Barrel
(3) Trunnion
(4) Muzzle attachments
(5) Bolt
(6) Bolt carrier
(7) Gas piston
(8) Trigger
(9) Hammer
(10) Disconnecter
(11) Buttstock
(12) Pistol grip
(13) Forearm handguards
(14) Magazine body
(15) Follower
(16) Floorplate

5 unless you are using a muzzle attachment, Then it has to be 6 (Or Just use a US made Muzzle attachement).
I mostly go with
1. Hammer.
2. Trigger.
3. Disconnector.
4. Buttstock.
5. Pistol grip.
6. Handguards.

If I want to use a Foreign Stock set (Like I nice Russian Laminate set) I use
1. Hammer.
2. Trigger.
3. Disconnector.
4. Gas Piston.
5. Pistol Grip (Z-Recto makes a nice US made Laminate PG that matches the Russian stuff nicely).
