AR noob here, just bought a norinco 10.5 and I opened it up and it's full of white powder similar to flour and a cloth bag that contained the powder until it was tore up by the BCG moving from my racking the bolt after taking it out of the box.
What is this stuff? Is it some sort of anti humidity thing I was supposed to remove? If this is not normal I can post pics of the inside of my AR full of flour like stuff....
