WHAT DOES RED ARMY STANDARD 7.62×39 MEAN?

The fee was deffently high and go figure suitable just after I ordered I found 1000rnds of unfastened pack 62gr lake city for the same rate as a single tin of 420rnds, but getting 556 ammo today is deffently of venture of discovering it and its price! Hopefully all this Bull will be around soon!Hello, Armed forces Member Bass Professional Stores is
