I think jim,not to familliar with the chineese stuff,but the black handled 56s ones would fit regular akm's.
The ones for the Poly Legend are the older milled style.And MAK 90 was a mix of them all.
Basicly the MAKS were neuterd anyway so its what you put back on them to work.A lot of the maks had neuterd spikers.
A lot of guys use to use Bulgy milled pattern front sights and gas blocks to de ban them(ballel dia and retainer pin location the same) and they used the first style bayo pictured.
