So I did a gun deal today and got a Chicom sks. I've been doing research and found that due to the five digit an and no tula marking it the /26\ on it, it's known as the "ghost gun" of sks's. Meaning that it was the first run of SKS rifles that were truly made from Chinese parts. Blonde stock with no sn. The bayonet is a screw swivel vs the roll pin and a spike bayonet. It is import marked but wth. Now this is all speculation on my part since im new to the SKS world. If anyone can help me, I'd really appreciate it. No sn on bolt.
