There are some good choices out there now, but my vote for the best all new standard production semi auto AK variant being made today, would be the Arsenal Inc SA M-7. They are built using brand new Bulgarian Arsenal components, and the rest of the components are made here under license of that firm. It is the only U.S. made AK that is licensed by a former eastern bloc AK manufacturer (Arsenal of Bulgaria). They are the only standard production AK in America built on a forged, milled, and fully heat treated receiver (and again, it is licensed by the Bulgarians). The finish is the phosphate base with black final finish method.
The SA M-7 is also not modified from something else, being built up from scratch in the U.S. as a double stack firearm (not having any mag conversions and such). Their fire control group seems to be the closest to the original Bulgarian semi auto FCG's. Their fire control group is being made under license of the Bulgarians using their methods of forging, milling, and heat treating.
Stock sets are made by using the same German polymer that the Bulgarians use, and as all other American components, are Bulgarian licensed.
Arsenal Inc not only makes their rifles under Arsenal of Bulgaria license, but also under their name (also under license). They even brought over and employ some Bulgarian Techs from the Bulgarian Arsenal to make sure the processes of the Bulgarian Arsenal are followed.
My vote, and in my oppinion......Arsenal Inc's SA M-7 (and other Arsenal Inc products):)
