Few things here....
Polytech and Norinco are basically the same... Just different factories with Polytech having a rep for more attention to detail and some better finishing, not a big deal to me. I'm not paying $1,500-$3,000 for a polytech when I can have the same gun made by Norinco.
Someone said something about the Norincos brought in that weren't Kengs Polytechs were the cheapest AKs? I beg to differ and highly disagree. All of the Norincos were imported to the USA by one importer or another, they are all Norincos thus all the same when it comes to build specs. Norinco didn't do anything more special for one importer than another.
Chinese AKs are def some of the nicest AK platforms out there. They are factory built like tanks. They have Chrome lined barrels unlike the Yugos. And they are regarded as having one of, if not the best FCG (trigger) of any AK variant.
Debanning them can be a major PITA if your anal or it can be easy if your not
It can get very frustrating if your trying to locate all true and correct Chinese parts for the deban, trust me I know. But you can easily buy a type 1 Bulgarian FSB and GB and your bayo attachment is up and running...
I have several Chinese AKs... The top one in the attached pic is a Mak90 that was debanned with Bulgarian Parts. The lower is a Mak bebanned with true Chinese AKM FSB and GB.
The prices of Maks are going through the roof nowadays as they are true factory built military AKs that kick a$$. With a little bit of time and patience you can deban that Mak back to its former glory. Whether it be a spiker deban or bayo deban.
I think if SHTF I would grab one of my Maks over any of my other AKs.
