I've just come across this, the g&g ak12 or gk12 as it labeled, and on paper looks as if it could be good; Steel bodied, actual quick change spring, mosfet and stop on empty.
Steel and stop on empty has me very interested but I'd be also like to know of anyone has any experience of ak12 platforms regards handguard etc as there's lots a out for other ak platforms but I've not seen any for the 12?
