Couldn't care a flying turd about a little casting mark unless it was sharp and cutting my hand or something actually impacting function or durability. I'd blame this on all the sexy photos at Festoolusa but lo and behold, they actually have a photo of a casting mark as well, scroll down to the miter lock detail shot http://www.festoolusa.com/power-tools/miter-saws/kapex-ks-120-sliding-compound-miter-saw-561287 So can't claim Festool was hiding it, it's shown plain as day for anyone who might obsess about such things. Can we get back to how it actually works?
