For those who don't know, there's a new supplier out of Korea making AK mags.
I picked up 3 ten round mags, since I use them in my AK mag SKS'. They were 10 bucks each, and most online suppliers carry them now.
They are pretty nice. I have pics below comparing them to a Chinese 5 round (which you can fit 9 rounds in, 10 if you shave the follower), and a Romanian 10 round. First thing to see, is they are a bit taller than the Romanian 10 round. They are all steel construction, including the follower. They are painted black, instead of blued metal. The sheet steel used is thinner (as expected), but the construction is excellent. The feed lips are double walled, the rear "tab" is a machined chunk welded to the mag, and the spot welds look perfect. While not feeling as robust as an original mag, I feel the precision of the construction on these mags make them just as strong.
Fit wise.... they are a little tight locking in. Seems like the rear spring latch has a hard time locking the rear tab. I might need to just file the rear tab a little...it's probably a tad thick.
