My NHM-90 has a receiver with a solid slanted rear and cut outs for the underfolding stock on the side of the receiver. My MAK-90 and MAK-91 fit my NHM-90 stock like a glove. I subscribe to the theory that they were going to be underfolding stock receivers, but instead of the holes milled in the side, one was cut in the rear. They shoot tighter groups but I don't know if this is because of better/heavy barrels or longer sight radius of the 20" barrels.Īll the milled receiver post ban rifles have the slant cut with round hole in the rear of the receiver. My NHM-91 and MAK-91 have barrels heavier and longer than MAK-90's. All after this bunch had the threads turned off the barrel. Just spray paint a milled MAK-90 black like the Bulgarians, and you will have the best finished AK imported with the best trigger pull.Īll Chinese MAK-90 rifles that were in the first bunch imported/in customs right after the 1989 ban had threaded barrels.

The trigger pull is the best of any AK imported into the US, yes even better than the "holy grail" of AK's, the Bulgarian SLR-95. The fit and finish of Poly Tech rifles pre or post ban are the best of all Chinese rifles imported. The barrels of milled receiver MAK-90 and 91 rifles are not threaded. The post ban models MAK-90,MAK-91,AK Hunter and Poly Tech Legend pre bans have the 386 in a oval. All the milled receiver Chinese rifles have 386 in a oval.
