    -Upper arrived in excellent condition
    – Had zero dings or scratches
    -No lose parts or rattle.
    -Feels solid
    -Looks awesome

    -Upper felt gritty, and needs a good scrubbing.
    -The lower portion of the feed ramp appears to have some excessive burrs. It worries me as this may cause the round to not feed properly. It might need to be polished. I would have given it 5 stars if it wasn’t for this issue.
