I believe that LMT will be reported in time...remember, it's only been out for 6 months or so and LWRC has been out over a year longer. It will take time. With the economy and other factors, this might take more time than the LWRC to have an accurate and unbiased report. That said, I too am looking forward to seeing how LMT works under hard use. I know that the factory has used and abused this piston. That is another reason I decided to buy my LMT. They took their time releasing this version trying to make sure all the bugs were worked out prior to selling to the public. I am one of the first to get mine and I did have an issue with the failure to feed. It was traced back to the gas port size. I was using some old red and white box PMC ammo. When I called and talked with Gene Swanson at LMT, he said that all the ammo used by LMT was much better quality 5.56 and this was the first time he had heard of short stroking. He had me send in the upper and returned it back to me in a week. I haven't had any issues with it since and Gene assured me that all versions since mine have had slightly larger gas ports to accommodate any and all ammo. I have since shot Silver Bear, Prvi (55gr), and the older PMC and no issues at all.
I too would like to see and hear someone taking LMTs Piston upper and putting it on an full auto lower and really running it hard. Maybe using it suppressed also at the same time. I know that LMT has already shot over 10,000 rounds (mostly full auto) through their own Piston, but that is not the same as others here doing their own testing.
Has anyone been to a class or two with their LMT??? If I could afford it, I would not hesitate to take mine and run it through the paces.
I went to one of Pat's classes and shot next to a guy using the loaner LWRCi gun. That gun seemed to choke on Wolf 55gr - it was the 10.5" gun too. The guy shooting it wanted to use it since he had an early LWRCi gun that was not very reliable in the configuration he was using. I think Pat said he was going to call LWRCi and talk about why the gun was having trouble. FTEs if I remember right.
Spooky
my interest is strictly in the differences between an LMT and LWRC piston weapon. Are they identical systems, or does one have mechanics that stand out over the other?

LWRC has 3 pieces to their 'piston' system and you have to take off the top rail to access it. That said, their piston system sits lower to the bore and under their top rail.
LMT only has two pieces to their 'piston' system and can be accessed by only removing the gas cup. BTW, that same gas cup can be turned upside down to block the gas port from the barrel to make it a true single shot rifle. LMTs can also be changed quickly to different calibers without changing the entire upper. As a matter of fact, their entire upper is a true one piece billet and extremely stiff and well built. You can even change back to their DI system with just a barrel/BCG change.
I have nothing bad to say about either system. I just bought the LMT because I liked the idea of changing calibers/systems without keeping complete separate uppers. I really like my LMT as you can tell, but I'm sure if they weren't available, I would have gone with LWRCI.
