Cyma internals are ok but it also depends on your luck. Some older runs I've seen still shoot without any intervention into the mechbox, some crap out after 2-3 mags. Zinc alloy-pot metal receivers is something you should leave behind when there is access to steel/aluminum. Cold bluing them is a pain, they break easier, they feel different to touch etc. etc.
