So I was thinking about building a gun so I decided that an ak47 was probably some what easy for a beginner. I know this is probably a noob question but I know there are different countries parts kit but I was wonder if that is the same for receivers and if for example I buy a Polish parts kits do I have to buy a Polish receiver if there even is such a thing. I'm going to get a receiver blank and drill the holes. Also I was wondering if there is just ak47 receivers and no country attached to them if I have to drill the holes differently for and Polish parts kit then a Romanian parts kit. Thanks in advance I have been researching this all over and I have not found the answer. Sorry if this is a noob question but this is my first gun which I am going to build.

An AK47 is the milled receiver model, the AKM uses the stamped receiver shell with machined trunnions rivetend in. You are building an AKM, not an AK47 if you are working from a blank.
Fixed stock models, the majority all use the same basic receiver. Underfolders, there are several variations in the rear cutouts for the stock and those have to be matched to the specific stock used. With an actual blank you are cutting these holes so the trunnion is used as a pattern anyway. On a commercial receiver or a flat you fold they have to match as manufactured.
Then there are the Yugoslavian AKM variants that are based on the RPK receiver, which has an enlarged area on the front trunnion that needs a matching receiver. Chinese stamped AKs use a thicker steel in the receiver, so the inside is narrower and the trunnions are too.
Although most European AKMs were built to a standardized pattern (Yugos being the exception) there are plenty of minor variations. You have to match the holes in the receiver to the existing rivet holes in the kit pieces, for example. Again, with a blank matching them is SOP. You will need the kit before you can start on the blank.
On a standard fixed stock AKM receiver, when dealing with US made items anyway, designating them a Polish or Romanian, etc. generally just refers to the selector markings. Like you can get an HK lower marked SEF, SOU, bullet pictograms, etc. Same functionality and interchangeable, but the markings are different based on country of origin.
There were/are some receiver blanks imported from the original AK maker's country, Hungarian and Polish mainly, so those of course would refer to actual country of origin even though they will work the same.
