    2) the rear of the teflon-chromed carrier has "pads" which keep the carrier more centered in the receiver.

    I have about 500 rounds through mine so far, and it shows some superficial wear on the leading edge of the receiver extension, but it hasn't visually changed in about 250 rounds.

    Had a LWRC M6A2 upper. The quality of the product was great. Never had a problem with function. Carrier tilt doesn't seem to be a problem. Unfortunately, the recoil for a 5.56 is too much, especially if you use an optic like an ACOG TA31F. If you want a piston gun, try a Robinson XCR. If you want an AR, stay with DI and use adequate lubrication.

    It appears it has all much been said. Especially for someone just now getting into the rifle system, buy a quality DI and spend the extra grand on ammo and get good with it.

    I never wanted to experience a failure or stoppage down the road, thats why I made the buffers. Tilt is not okay, by any stretch of the imagination or for any length of time IMHO...
    There are systems that can put certain parts through added strain, over that of the DI system. Preserving those parts is the best anyone can do, given the fact that they would continue using a piston gun.

    Out of curiosity does LWRC use a different bolt or does it a standard style bolt?

    The thing I don't get is that some piston examples exhibit tilt while others in the same brand don't. is it an anamolie or what I mean I don't get it. I am beginning to re thing my getting an LWRC. I wanted the reliability of the piston system for sbr / suppressor purposes but even then is it worth it?

    Go with gas

    Why fix what isn't broken?

    You will have to clean it either way just not as much with the piston but if you clean it more often and it breaks you may what is broken and how to fix it easier. With a piston chances are you will not know the gun as well due to the lack of field striping/cleaning.

    I could be wrong but I think grant at G&R tactical is building suppressed sbr,s uppers with lmt enhanced carriers. Might be worth checking out.

    Maybe I'll check that out I will not be in the market for an SBR upper for at least 15 months as I'll be in afghanistan for a year. Maybe I'll go see if there is another colt in at my store and switch layaways again on the LWRC. We'll see

    15 months if AWB2 hasn't by then I would be looking for a FN scar or an ACR
    you would have enough coin for that
