Inherited Norinco 5.56

So my uncle gave me a rifle and said I can keep it or sell it and to be honest I know a little about them but not a lot. It’s a Norinco Mak 90 in 5.56.

Now I always hear things like”pre-ban” and I know values change but I honestly lack the knowledge about the value of this rifle and how I would even label it if I was to sell it.

attached are some pics if anyone can give me a better understanding of the history of this rifle and value I would appreciate it.

btw it is straightcut receiver and the homemade wine is not for sale.
