    Excellent Product

    Received my DEMO BCM Upper Receiver and it barely has any noticeable scratches or defects. It was a steal at the price it was offered at and I look forward to purchasing more BCM products for my AR build.

    Excellent fast service

    The only thing that would have made my experience better is if there was a store attached to the physical company building because I'm local. Order was processed and received in four days. Blem product had two visible scratches which previous blem did not, but it came as advertised and is a very well made product. I've never had a problem with the first upper I purchased and this one will be a project with my daughter.

    Very tight fit

    Shipping was fast and i could find no blemishes on the upper.
    I had a time getting the upper hot enough to slide over the Daniel defense barrel extension i had.
    after warming on the stove burner for a while and freezing the barrel they slide together.
    I honestly prefer the normal fit of most uppers
    I have a older BCM upper that fits normal
