What he said, I agree with getting a 100% receiver for the first build or even if you just plan to do just one build, a lot less aggravating.So, I get any AK 47 style AKM 80% blank and have at it? Anything else I should particularly know about in the acquisition of parts etc. Such as a particular barrell etc.
But yes any AKM receiver, blank or flat will work.
As for the barrel, any AKM barrel will work. If you get a kit and want to make sure which barrel, just ask and you'll get an answer.
