THE IMAGE ABOVE IS A PAID ADVERTISEMENT
Are the gas tubes and bolt carriers interchangeable from Norinco 84S and other 762 Chicom AK's ? Such as 56S, and polytechs. I think they are but wanted to know for sure. Obviously the bolt is different so I am not sure about the carrier.

Im almost 100% certain the gas tubes and carriers are the same between the two calibers.Polytech and norinco stuff is the same as well.Just made in different plants to the same specs.

Thats what I thought too. Picked up some 84S parts that should be here soon, and figured they would work for both calibers. I have only one 84S but afew 762s so it would be nice if parts were interchangeable.

I know the barrel journals are the same. Therefore the trunnions should be as well

I don't think they are, but I have never really messed with them so i can't say for sure.

The bolt body on 56S 223 cal is smaller than 7.62 bolts in diameter. So carriers are different.
