The bolt is even on the left where it belongs. The Soviets moved it to the right, so most operators had to move their right hand away from the trigger to chamber a round.
And I’ll bet the machined fits are a light tighter than the AK.
Like jet fighters, wanting bombers instead, Hitler resisted automatic or semi-auto rifles thinking the Mauser bolt action was good enough for him, well it’s good enough ... which is a conservative position if you think about, even if cuckoo.
