    Yeah, I would not want to slam anything. Not really sure what else to tell you as there is only one way to get a barrel in there where everything lines up and you can tighten the retaining screw.

    Sounds like the lugs arent lining up. Chamber might be out of spec. Contact Terra for sure. She'll take care of it. Robinson is turning their own barrels now, so they will want to know sooner rather than later if something is off

    They are doing this *now*, or they just have plans to do it? I thought that was still just a long term plan sort of deal.

    Re: bolt won't close on a new heavey 5.56 barrel

    To clarify for all you guys -

    Jim had bough an extra barrel. When he tried to install it, nothing would meet up right. We figured out he needed the new piston installed, since his original barrel has an old gas system on it, and the old piston on his op rod was not compatible with the new gas system on his new barrel.

    Problem solved.
