I have a Century Tantal that has a Hogue grip, Russian wooden stock, Russian lower and Ironwood upper handguard as well as 3 East German Bakelite mags. It has a 1:8 twist barrel and I have shot both Silver Bear and Russian Surplus - 100% failure free. The sling does not come with it.
I also have some Russian surplus that has been removed from the SPAM can and placed in ammo boxes. It is still in the original paper. I could sell you some if needed.
