Cross is solid for me. I loaned out my 660 blue clone with a ported cross top end and let him rip on it for his business for a couple weeks with a 36" bar/chain...he put alot of mix thru it and ran it hard...i pulled the muffler off and its spotless

Thanks for the reassurance. Kit looked good.

Don't know, I do know I have never seen a piston wear that far in 50 hours and I know my old original from new (model release) 2159 is still pretty tidy looking outside, but has done a gazillion hours and wore a piston similar to the one you removed.
If your buddy bought it new, then you know the history- if he did not buy it new, any monkey could have been in there, fried a piston, cleaned it up a bit, found a well used secondhand piston, threw it in got it going and promptly sold it to your buddy?

Saw was bought used from someone he knows well.

Perhaps that someone he knows well- needs asked some hard questions?
