Re: Norinko SKS
I'm confused, are we talking AK or SKS. The SKS has been around for a very long time, long before the invention of the 5.56X45 caliber round. Not only that but to my knowledge the SKS was manufactured only in 7.62X39, as was the AK47. Even when the Russians downsized the caliber in the AK74, they went with their own unique 5.45X39 rather than 5.56X45.
Might you be dealing with a Saiga? That's an AK style rifle that is available in several calibers including the 5.56X45/.223.
