I have heard good things about the PWS conversion, and the one I played with (their "Diablo" upper) ran like clockwork. However I don't know enough about how their system compares to the other conversion kits to form a real opinion.

I will say that my POF upper runs like a scalded dog and has never given me a hint of trouble, even with really dirty ammo. I run it dry and have done no maintenance on it other than to run a boresnake down the barrel every 500 rounds or so. I have heard bad things about POF from time to time but have never experienced them!

What is the goal of your conversion? Less cleaning? Greater reliability? I have 4 other ARs besides the POF and feel no great need to convert them to piston operation.

The #1 item on my list for all of them (except the .458 SOCOM....sigh) is the PWS FSC flash suppressor/comp. The first time shooting a rifle with that thing on it was downright WEIRD. The muzzle climb/recoil is improved so drastically that I thought the gun was broken.
