Has anyone built a version of the HK416?  From what I understand it has a piston operating system rather then the gas tube.  Any information on this would be greatly appreciated.

You can buy the parts kit for it if you wanted, you'll see them forsale from time to time. Usually all you need is a lower, as the HK lowers are full auto. Price isn't pretty, $3-$5k for them. Just buying a name. Build one using a POF upper or something if thats all you really want is a gas piston upper.

Yea, i'm just wondering what needs to be done to convert a gas tube ar to a gas piston version.  I have a RRA lower and all components for a complete gas tube Ar-15, so I was wondering what I need to change out on the weapon.
