cleaning after corrosive ammo

First do an online search to find out if that ammo you have is in fact corrosive. I seem to remember that all of the KA head stamped stuff is, much of the PS stamped stuff is not. Immediately after shooting run some Windex down the tube, then at home strip it down.Make sure that you clean the op rod, gas cylinder, bolt, and receiver too. The primers are what is corrosive so whatever got firing residue on it should be cleaned, not just the barrel.
