Yes, was speaking to 5.56. 5.56 VZ 58s didn't come about until CSA got the rights from CZUB who was pushing the Bren, and previously other rifles, in that caliber and didn't want the competition/a lower cost opt-out...
My understanding is that Century has had these kits for years, like 90s to at latest early 2000s and paid an extremely small amount of $ for them.
I don't anticipate kits becoming available at sub $50 or sub $20 (depending on who's speculating) that Century paid previously... But then I also don't know how many kits they have on hand either. So someone might build in the US, but due to Czechpoint/CSA's previous litigious nature, I don't think it'll be for/until another decade when their patents expire... But we'll see...
I'd personally be stoked to see a screw in rather than press fit barrel option/configuration/receiver. I think that alone would do wonders for bringing this weapon into the modern age...
