AKstuff has been selling them for a while. They are Russian made and they have 2 or 3 models per caliber, some are full polymer and some have metal reinforcement.

I saw the same thing from Atlantic--these appear to be a second generation, and they at least "look" like magpul level quality. There are very few videos out there that are more recent, I don't know how well the first gen ones did. The most recent video I saw was for a clear one, and the chipping wasn't surprising IMO (un-reinforced feedlips).

Can anyone comment on the second gen, solid/black, 30-rounders in any caliber?

PUF and AC-Unity appear to be the best game in town for reasonable-ish priced 5.56 mags these days, but only saw the PUF ones advertised recently.

I have 5 Puf 9mm mags on my Saiga 9. I bought 6 of them, 5 black and 1 transparent. This transparent one broke on the first shot. A part of the left lip gone with the carrier. The other five work flawessely.
