Maybe maybe not... This is a brain smoker for sure. Chinese one looks to be the typical hump back. Plus the lower bars on this one don't extend into the front like chinese. Looks more like a Yugo steel mag with the 2 bars coming up short on the bottom. Could you post a picture of the bottom and the other side and looking at the back?

sorry I realized you did do the other side. Wondering if there are any other marks on the spine but can't see it real well. Also looking at the front and back to see if anything.

Yeah I am baffled on that one for sure. It is different looking all around. I would guess 5.56 if it is from yugo as I don't recall them doing 5.45 but looks nothing like their m85/m90 mags. Serial number is also interesting. And a pretty big number.

Possibly but the mags I have seen on NK are more like the Chinese 74 where the two bars at the bottom extend down on the front of the mag.

The cut is the ejector relief I believe. The follower in the mag looks more 5.45 than it does 5.56. What do es the follower look like in the bak mag?

Here's picture of the follower

That looks like the 5.56 follower so my guess is that the other one is a 5.45 just no clue where it is from.
