I don't have quite the disdain you have when it comes to AR gas pistons and Kalashnikov rifles, "we have discussed this in the past". I have had better luck with gas pistons in the AR platform when running different types of ammo that has different pressure values. The direct gas system has a shorter variance of pressures that will work reliably compared to a gas piston. The other opinions I agree whole hardily. I just thought it was amusing to see the difference of opinions people can have no matter what their experience with the military rifle concepts has been. This is why I believe shooting competitions are a good place to start when comparing rifle concepts. Not the end all of rifle concepts but a good start.
