No one really knows why the Yugoslavians didn’t chrome line their bores, they certainly could have. There are two guys who I know who have spent time at the Zastava factory, Dan Shea and Eric Kincel…they might have gotten the word as to why the Yugoslavians decided to not chrome their bores. It’s interesting that when they started producing 5.56mm AK’s for export, the M90 and the M21, that they started to hard chrome their bores.
As far as an up surge in demand, you’re seeing that across the board on stuff.
The vast majority of rifles that made it to the US to be turned into parts kits had crap bores. They were captured from Serb militia in Bosnia. The lack of a chromed bore + use of corrosive ammo by thugs who were too busy ethnically cleansing their neighbors to provide routine maintenance on their rifles = sewer pipe barrels. They had time to carve up their stocks with a lot of Serbian propaganda though. Lots of those kits came in with “trench art” on the stocks.
The Century guns were built with a Green Mountain barrel made at a very low price point. I’ve seen some with out of spec chambers and an issue where the rifle will discharge when you engage the safety. I’d avoid the Century builds.
Atlantic had some built up with unissued Zastava barrels, which should be very nice, but not cheap either.
As far as being more accurate…that’s going to be an individual case by case basis. The Russian, Bulgarian, and Polish cold hammer forged barrels are really good.
The Yugo AK’s are the ONLY ones that the underfolder variant is more comfortable for me to shoot than a fixed stock. For whatever reason, the Yugo fixed stock M70’s have a very high comb that smacks up against my cheekbone, which does not allow for a comfortable cheek weld when using irons.
Real Zastava produced AK’s that were imported in the 80’s by Mitchell Arms and American Arms are very high quality, and interesting from a collector’s point of view. If I were procuring AK’s for a military unit or a PMC, then they’d be down near the bottom of the list because, as others have noted, they use proprietary parts and have a lack of chrome lining.
These pics are from 2006, I traded off this last real Yugo underfolder a while back to a friend, and I miss it occasionally, but it’s still in the “family”. The pistol grip is a bring back from Iraq, either a Yugo or a Tabuk.



Again, when the Century Yugo M70’s first came out they exhibited a better build quality than we’d expected from Century, but over the years, I’ve come to the realization that while many, many of them work just fine, their is a much higher chance of getting a lemon from them than there should be…and I just do NOT trust the Green Mountain barrels.
