OK, I was running along smoothly with my latest build when all of a sudden I came to a snag. I attached a Ewbanks receiver onto, what I had thought was a Romanian AK. When it came time to fitting the bolt carrier/bolt, the thing would not seat all the way...so I thought it must have been the rails being not level or set too low. So I eyeballed it and things seemed level enough. So I took the bolt out and just tried installing the carrier, when I realized that the carrier front (where the piston attaches) snags inside the FSB. So I thought the carrier was bad, so I tried it out on one of my Romanian "G" build...fit like a charm. Anyways, all I can describe about the kit is that it was built in 1970 and has a triangle with an upwards-pointing arrow. Do I have the correct bolt carrier for this AK, or were there different carriers for different AKs? Sorry if this question is dumb, I'm just stumped at the moment.
