Hello, I have a  Norinco BWK-92 Sporter and it's stamped 5.56 but the manual said .223 (I've since lost the manual, that was almost 25 years ago). I can't find any definitive answer as to whether it's 5.56 OR .223 Honestly, I'm just curious since I have .223 ammo though I have a DR200 and AR in 5.56 but feed it .223 Can anyone point me in a direction for the answer?  Thanks....
Sorry for the links, I'm new and figuring out how to post pictures directly.....
