    As has been stated by Doc Roberts and many others, piston ARs are only really "necessary" if you're shooting a full-auto suppressed SBR. And even for these guns, the piston is there to impart that last percentage of reliability under very harsh conditions and firing schedules. Most AR owners will not visit this part of the AR performance envelope, let alone live there.

    And in terms of cleaning, it is not necessary to get a DI gun to "white glove" condition. Wiping down the BCG and running a couple of patches down the bore are pretty much all you need to do. The bigger issue is making sure you use plenty of lube, which is not rocket science.

    My only piston gun is an LWRCi PSD in 6.8. It has an 8" barrel and almost no barrel past the gas block, so the piston does help to impart reliability across a wider range of ammo. Other than that, even my other SBRs with 11.5" and 12.5" barrels are DI.

    I will echo the question of the need for a piston AR, as well as the support of LMT.

    I have an LWRC 10.5" upper that has over 10k in rounds. I just ordered the newer 12.7" M6A3 upper with the adjustable gas system.

    IMHO, the only real advantage to a piston system is its ease of cleaning. I was seriously considering another DI upper until I decided to clean three of my DI guns. That convinced me to get another LWRC - mostly because I have had a lot of great Customer Service from those guys and they were available.

    A friend of mine recently bought an LMT MRP 16" piston gun. It's a lot smoother shooting than my 10.5" piston gun. I do recommend that you decide if you really want or need a piston gun because they are pretty costly. IMHO, you can't go wrong with either LMT or LWRC. I own products that are made by both companies.

    Good luck!!

    i have an m6a2 upper for my sins, it's ok, 3 moa at best, not my go-to gun, i've seen the lmt piston guns and they look very well made but i've never had a chance to fire one.

    the m6a2 cleans up very quickly after use, but if you want to get into the operating system to clean that, i find it a real pain removing the two side rail covers in order to get the top rail off. when i timed the whole thing it actually took longer than cleaning my colt

    In my humble opinion, I consider the latest LWRC weapons to be among the best AR15 platforms out there.
    Extremely well made with all high end parts. Exceptional accuracy and as relaible as any AR out there.
    LWRC had a few growing pains in the beginning but the weapon that they put out today is impressive.

    I own 2 M6a2'S and just got an M6A3.
    Very satisfied.

    technical curiosity. but it's a 'want', not a 'need'.
    by owning and shooting both systems, i can base my opinion on my own observations and limited experience with the two systems. i like finding stuff out for myself, whenever possible.

    Another advantage to the LWRC M6A3 is that you have an adjustabel gas regulator. If using a silencer you can adjust gas port size and then go back to normal when the can is off. Solves a lot of over/under pressure issues when using the same gun as a supressed weapon and without. You dont have to tune the gun specifically for one or the other.
    Also you can raise your gas port size when the gun is shooting cheap low powered ammo.
    You can even close the gas port completely off and have a single shot rifle.
    There are many high end ARs out there that one can buy. Direct gas or Piston. Im sure that you would be happy with most of them including LMT.

    LMT DI stop screwing around and spend the rest of the cash on ammo and training/competing.

    As by looking at my screen name you might find a little bias----only because LMT made my first AR----
    I think LWRC is a great company, however if you're going with a removeable top rail vs. LMTs mono-rail, get the LMT. The last LWRC's top rail I saw did not line up with the receiver. In my experience, 1/16" difference in rails can cause havoc if you're bridging optics or forward mounting. I do not have an MRP or LWRC, however, I think you'll definitely love the system from LMT. Apparently LMT's piston system is extremely smooth in cycling, not harsh like others.

    The new LWRC guns run, and they run well. They have CHF barrels, and after an 800 round a day class, they not cleaner but are easier to clean. This is due to the carbon not being baked on the bolt and carrier.

    DI guns are a completely proven system. LMT is a tier 1 company. Actual milspec and quality throughout. No batch testing of parts like some other manufactures. I have read an interview with John Noveske where he makes a strong case for DI being a superior system. His Switchblock answers the concerns of shooting suppressed.

    At this point if you go with a quality manufacturer and properly maintain the system I would happily run with either.
