    I just wanted to say thank you to the hard working staff at Durkin. I had a few questions before I ordered, and Lauren answered each one, honestly and professionally.
    After placing my order, I felt confident that even if they could not fulfill my preferences, that I would still receive a quality product and I would be happy with it.
    Wow, was I impressed! The receiver is a good old reliable mil spec with the forward assist, the barrel the same. The hand guard though is what I did not expect. It’s design is pretty darn close to what I spent days looking for, but couldn’t find.
    Oh, and it only took days to arrive after I ordered it!

    Thank You again, I will be ordering again soon.
