OK I know how many parts I need to be compliant, but what parts are everyone using?  Im going to build a Polish underfolder and a Romainian RPK 47, once I get back from my year in Iraq.  So I figure the G2 fire control parts and US Receivers, that gives me 4, what about the other parts needed, if I want to keep the orginal furniture and have a threaded muzzle?  Do I go with a US muzzle attachment and gas piston  or mag followers?  

A few options
1. Receiver, G2, Piston, Grip
2. Receiver, G2, Piston, Break/Flash Hider
3. Receiver, G2, Break/Flash Hider, Grip

Im sure there are other combos but i would say those are the most popular ones. I have all the parts listed on my site www.MidwestArmory.com
Good luck and stay safe

My Yugo M70's will have:

Receiver
Mag Floor Plate
Mag Follower
G2

generally your parts will be any of the following:

receiver
hammer
disconnector
trigger
gas piston
muzzle attachment
butstock
pistol grip
handguard
mag follower
mag floorplate
mag body

i don't do the mag parts because it is too confusing with all the foreign mags around.

least noticeable choice seems to be:
trigger
disconnector
hammer
receiver
muzzle break
gas piston





eta: pistol grip in the upper section.
