The AK has a Gas Tube, Bolt Carrier, Piston, Bolt, Firing Pin = 4 parts. Less parts on the AK therefore it is mechanically simpler.

The intent of using a gas piston compared to the DI is to reduce fouling during combat. A gas piston AR is useless to law enforcement or civilians as they are not operating in the harsh environments that our troops operate in.

I have had the SCAR in my hand as we have demoed a couple of times there are still some things that are being changed on it on being the bolt handle. But overall the weapons operation is excellent. I am sure that if the SCAR had 50 years of development it too would changed in configuration. Think XM177E1 to M4A1 similar looks yet completely different systems each with there own problem.

I understand you stance as being pro AR system but the AR is not the only thing in the world and I have built over a Thousand AR's in my life so far.

I'm sure you built over a thousand AR in your life time.

Piston doesn't reduce fouling in a gun. It change where the fouling is located. The fouling doesn't magically disappear in piston gun. I shot my AKs and you know where all the fouling is located? The piston and the piston tube.

The SCAR use a modified AR18 action. It's nothing new. Just a different stock.

I agree that it is nothing new to the SCAR gas system. It is true that a piston system can take more abuse then the DI system. The DI systems has always had an inherit weakness to it between the gas tube and the gas key. Both parts are just a flimsy design more prone to damage in the hands of a soldier. But again even though the DI system is fragile it is not a problem for both civilians and law enforcement. As for the AK fouling I had some AK's that East German ammo was used on which is very corrosive. The piston was frozen in the tube we so we just hit the bolt handle with a rubber mallet. The piston came free and the weapon was fired right after with out any other service done to it.

Don't get me wrong I love the AR system as I have been working on them since 1975 but there is always room for improvement.

I don't know how a kid would mess up the gas tube and gas key. It's not like they can take it apart without tools.

Come on if the AR15 was so prone to breaking we would see more dead kids coming back home from over 8 years in Iraq. Your chance of getting killed in a major city like DC is higher then your chance in Iraq (at the height).

Again fouling doesn't magically disappear. It just get relocated. Fouling for AR15 DI is in the bolt because that's where the cylinder is located and that's where the gas goes in. Fouling for rifle piston and not just AK but all piston rifles is located in the piston and piston tube. That's where the gas enter and stop.
