Also purchased a 527 rail for it.
I thought when i asked the question that they came in 222 and 204 and maybe one or two other cartridges in the past, but after a quick search i believe you are right. I have the carbine, which comes in a handful of calibers, but it appears that FS models are only 223. And only recently in a 1:9 twist...adcoch1
I think the CZ 527 fs only comes in .223. If you're looking for a full stock rifle in calibers like .243, .270, .30-06, or .308 then the CZ 550 fs would be your choice.
The .300blk could be achieved with a barrel change on a .223 model since they share the same bolt face. But for what it's worth, the two calibres you mentioned aren't all that popular in Europe.I have the Carbine in .223 and it thinks it's a varmint rifle. Your rifle is a real beauty and a shooter too.
I think CZ is really missing the boat by not chambering the 527 in .300 Blackout and 6.8SPC for small to medium sized game.
