Hey guys, just had a quick question concerning the confusing topic of 922r compliance. I have a Norinco sks, that I bought from a gun store, in original configuration with spike bayonet and all. Now I want to run it with the Tapco 20 round magazines, but keep it in the original stock. I have a Tapco gas tube and handguard, as well as the Tapco gas piston, and I was just wondering if those parts are all that I need to bring it into compliance, since as far as I know the Chinese sks's only have to have four imported parts replaced with US made parts. Am I right on this, or way off? I'm new to these forums, so thank you for your time!
