MAK90s are climbing in price, expect to pay at least high-400s (or more) even with the butthole stock. MAK90s were typically Norincos, while "AKS762 SP" were PolyTechs. Brand names are just symbolic...
If it has a straight-cut recvr - even better as a CHICOM butt will fit right up, if slant-cut; a bit more effort and $ to find the right buttstock to "blend in" with the slant.
Regardless - they are uber-well-made AKs. Get it if you can afford it as they will never, ever be imported again in any config.
If you don't - please post for someone else to score that bad-boi.
