Spit-balling curious since I am largely an AR guy but I toy with the idea of an AK now and then- have you any hands on experience with the Thordsen AK's to compare and contrast the NYLAK with?
I will probably build an AR in 308 before I mess with AK's but since you bumped the thread seemed a good time to ask.
I have not but I've held a thordson AR and it just left so much to be desired and well the cost vs the cost of nylak
