I gambled and got an almost brand new German made kit from IO when they ist got the last batch in. It had a beautiful bore and 95% finish. I didn't want an early version since I had a brand new/excellent CETME kit. I agree the Portugese kits I've seen form FMP are just as nice as the German made kits.
BTW - a couple of questions out of curosity on the I/O German G3 kits if you don't mind;
1) All part numbers match? (I know HK parts are date coded, maybe I'm thinking about serial numbers - on FMP they number the bolt head, bolt carrier, and a couple of other parts)
2) Have you measured the bolt gap ? If so, what was the measurement?
