I think I could be wrong. I know the AK-47 was designed by a Russian. Mikhail Kalashnikov invented the rifle.
But just because it was invented by a Russian in Russia does not mean that all AK-47's are made in Russia. So my comment about supporting Russia is only true IF there are any AK-47's still made on Russia. Like you said, some or all are made in Serbia, Egypt and Pakistan.
So I rescind my comment about supporting Russia. And what I meant by supporting Russia was buying arms that are 100% Russian made.
The Springfield Armory M1-A is a very reliable rifle and it is very accurate. It is the successor to the Garand M1 and that rifle is what was supplied to our soldiers in WWII, Korea and the first part of Vietnam. I'm sure there are a lot of other semi-automatic rifles on the market that are just as reliable as the AK-47 but I don't know enough about guns to rattle off a list.
