Side folders are SEXY!
However, if you had to replace any of the barrel components, you would have to use milled AK parts because AKM parts wouldn't fit. IIRC, the interior dimensions of the receiver also match the AK 47 spec, and an AKM lower hand guard requires modification to fit due to the thicker receiver, front sight block, and front trunnion. Chinese AKs also lack the sight rail common to most AKM variants but kept the double hook trigger and smooth receiver cover of the AK over the single hook trigger and ribbed receiver cover of the AKM. The Type 56 also kept the vented gas tube of the AK over the vented gas block on the AKM.
The Russian's, IIRC, didn't give the AKM specs to the Chinese as relations had cooled between them by that time, so the Chinese reverse engineered their stamped AK from the milled model.
I have to admit though, I have never personally held a Type 56-2, and my personal experience has been limited to the Modernized Automat Kalashnikov of 1990, although my underfolder is a neutered for import Min Shan Type 56-1.
