I know they use a mix of Polish and Hungarian kits along with OOW or Global Trades receivers but I'm curious about the other US compliant parts. How do they compare with the parts being used on the S.E.R.?

According to my manual:

Receiver
Muzzle attachment
Gas piston
Trigger
Hammer
Disconnector

But mine also came with a US pistol grip, which I will be changing out.
