What AK parts will interchange with a krink?

I have a bulgarian krink full auto chambered in 7.62x39 built on a chinese norinco stamped receiver. Would love to get some spare parts for the fire controls and wondered if krink parts are unique or are they the same as any AK47 fire control parts? Would like to get a spare bolt, fire control parts etc....

I know a spare barrel is going to be a challenge and is unique to the krink.


Thanks for any input.

A chinese receiver is made for a double hook trigger. The Krinkov trigger is a single with a faux rate reducer which only acts as a spacer in the Krinkov. The Krinkov doesn't have a real rate reducer like an AKM. If yours is on a Chinese receiver it might have a double hook trigger. The Chinese auto sear is sort of unique also. It's shaped like a milled receiver one but cut out to clear the center support and the spring hole is a bit different also to clear the center support. A standard Krinkov or AKM auto sear may fit but not a milled receiver one.
