Want to Sell Norinco 56S Sile blue bolt

I have a shooter 56S. Very exciting. Sile import, I like these. I like that the recoil rod is serialized and top cover serialized on the rear like AKM. Theres alot of small differences, blued bolt etc. I feel like the import markings are less visible on the rear of the receiver as opposed to under the front trunnion like most sile imports. Splitting hairs for sure but I like these better. I have 3 of them. These guns have MS prefix on the serial. I wonder if it means Min Shan. Possibly Interested in these Arsenal rifles for trade
