mnga sir silly question...what is a gas block???
Its the gas valve near the end of the barrel in gas operated rifles that divert and controls expanding gases from the barrel to push the guide rod to open the breech to cycle the weapon to load another round into the firing chammer. ( basically you see the on top of the M4 barrel a tube that goes back in to the upper reciever)
