I was wondering if anybody knows if circle ten ever made any mags other then black ones and if so, where I can find one?

Yep

Don't know

((10)) 5.45x39 mags also come in green or olive drab and plum.

Im sorry, I should have been way more descriptive. I meant to say in 5.45 and not new production. Specifically 80's production. I know most of them are circle 21 and others but im wondering about circle ten mags.

Plum ((10)) 5.45x39 mags are very rare, I've seen a couple for sale $40 a piece. The olive drab/ green mags might still be in stock with K-Var.

I also forgot to add the 45rnd RPK74 bakelite magazine. Most bakelite RPK74 mags will have a star and shield for the Molot factory and the Bulgarian mags will  not have any makers marking or a solid circle in place of the Molot symbol. This doesn't mean Molot didn't produce them for Bulgaria, I know it's a little off topic but ((10)) arsenal is the state arsenal for Bulgaria and I thought to add this bit of info.
