Get an AK with a stamped receiver, SS.
The milled receivers cost more, make for a heavier piece and take longer to cool down.
The Rooskies went from stamped to milled, then went back to stamped.
The only reason the Chinese (Norinco) still turn out milled receivers is that the process is labor-intensive and Norinco has an entire city of about a gazillion factory workers who need the work.
(Beetling brows ominously)
It used to be that the Norinco copy of the 1911 .45 was as good as the Colt production during the Korean War. Those particular Norinco products are so sturdy that they are popular for converting to the heavier bullet and powder cartridges. (Rowland model?).
Milled still looks badass though.
