Ar 15 Piston

Direct impingement works well. there has been no great improvement offered by the addition of a piston to the design, the #1 cause for failure in the AR15/M16 FOW is caused by the magazine,the piston system does nothing to prevent these stoppages.

Hmm, stoppages are caused by the magazine. Could you go into detail?
The magazines are flimsy, function poorly and load rounds into the rifle in a less than perfect manner. Most jams in AR15 variants are due to this problem, rather than actual failure of the mechanisms that make up the rifle itself.
So the Army went about spending millions of dollars soliciting offers from the world's big military arms manufacturers for a new enhanced reliability system, with consultation from SOCOM and many other users and the solution lies in an enhanced follower and stronger feedlips?
As I read in Patrick Sweeney's books, the piston seems like the answers to all of our prayers, but looks like it ain't. He says that with the piston, the gunk will only accumulate in another place, plus a piston driven AR means more moving parts, hence possibly less accuracy and it may trouble the harmonics of the barrel.
Personnaly I never fired a piston driven AR, but would love to get one (HK 416 or Massada)!
The AR15 was designed to use direct impingement. Any piston retrofit is just that, a retrofit. As such, it will never be anything but a piston slapped on a rifle that wasn't designed to use it. This will be a source of problems.
Now a piston on a gun designed to use it, that's where the benefits are.
Personally, I'll only own a direct gas AR15 if it is given to me for free.

Does that surprise you? No one's ever accused the government of being cost efficient.

A short stroke gas piston system has to have 2 springs. Because you lose the beneifits of the "self regulating" piston if the op rod/piston assembally is connected to the bolt carrier.
I admit they could have hidden the buffer return spring in the reciever, but the HK416 is was designed to be a "drop-in" upper for a Mil Spec M16/M4/AR15 lower.
The AR15 DI system does work well. But you definatly cut down on cleaning time with the piston system

I think the AR has a couple flaws. first is the magazine. second is the spring loaded ejector. the bolt has 8 puny lugs that can break off. the DI system isn't all that bad, it just gums up quicker, and my AR likes run with alot of CLP
