Rusty,

I haven't done one, but in amoungst John Farnham's "Quips" he stated that he hasn't seen a gas piston AR make it thru his classes without a serious breakdown. He believes that shoehorning the parts into a stock AR upper makes them too small for durability.

However, he is a big fan of the Robinson Arms rifle which was designed as a gas piston rifle.

Unless one is going to get rid of the operating spring in the butt of AR type rifles

I see no real advantage into going to a piston gun.

If one gets rid of the rear operating spring and put a true folding stock on it I seee some advantages.

Butch.... You're just not "hip"

The tacticool crowd know that the unburned powder build up will get you killed...

I know that the piston styled AR clone isn't new.

Ever hear of the AR-18? Easier to clean than the M16, but I would not say more reliable.

long stroke piston? like an AK
seems like that would be hard to invent for an ar.
and if you never had the bolt so gummy it wont work you have to be cleaning it a lot

If your gonna be dumb, you gotta be tuff.

I've never been in the military where you could fire several hundred rounds in FA mode but I have attended a few training sessions where we fired four or five hundred rounds a day. It doesn't hurt to carry a bottle of lube and give it a little squirt in the holes in the bolt carrier when the going gets tough, but saying that I don't believe I ever had a malfunction from a dirty bolt, they've usually been caused by ammo or magazines.

IMHO the real weak spot in the AR design was the magazines and recent upgrades have fixed a lot of those problems.
