I recently went through a K conversion on my CZ Scorpion. Really happy with how it turned out. Used the MI handguard and tri-lug barrel from In Lead we Trust. I put together a couple of videos of the build process as well as some shooting. I still think the CZ scorpion is one of the best bangs for the buck...really happy with mine! anyone on these fence of doing their own conversion, it's fairly easy if you have mechanical abilities.
