Update to my earlier response, I called CZ to check, they confirmed 100% that the downloadable list erroneously did not include the 223 model, it is in fact included in the rebate. If there are any issues when filling out the rebate after purchasing one in 223, they said to contact them at 800-955-4486 press 0 ask and for Dan.

It seems like the 600 Lux model in .223 is not on the rebate list.
Here's the models available to receive the rebate.

The 223 version of the 600 Lux doesn't qualify, that's why the listing doesn't note it. Their website https://cz-usa.com/2024-fall-rebate/ , has a list you can download and open in excel or a similar program, and it notes the only 600 Lux models that qualify are the 308, 30-06, and 300 winmag models.
