    **UPDATE**

    See Colt's response below:


    Good Afternoon Mr. ____,


    I have forwarded your picture to both the product service manager as well as our resident rifle expert. Both have agreed that your Bolt assembly needs to be replaced. I will send you a FedEx shipping label to bring the Bolt assembly back in so we can replace it for you. Which address would you like it sent to? Thank you for your pictures and your patience in this.

    Sincerely,


    Kara

    The thing that I find to be odd about the wear marks is that they are perfectly in line with the feed ramps. Are we sure it's a bad bolt and maybe not a problem with the machining of the feed ramps in the upper receiver?

    This doesn't make sense. For one, the feed ramps would line up with the other side of the bolt on the bottom, and two, this part of the bolt never travels for enough forward to contact the feed ramps

    This is why I buy from tier-1, they may not be perfect, but they usually go above and beyond with CS

    I'm sorry, I haven't slept in two days and my brain isn't functioning very well... Yes that is what I meant.

    Looks like the operator didn't seat the end mill all the way into the collet during a bit change and the CNC didn't know any better.

    Ah!! His name isn't really Scott, but yes... I agree with him most of the time.

    LMT is the "new bushmaster" in my opinion.
