    Package arrived with 95 cents "postage due". Not a big deal, just annoying.

    Colt upper

    Posted by christian reynolds on 26th Apr 2017

    The upper looks ok, not as nice as the socom I bought last year but still a good deal. I haven't shot it yet but I did notice the upper was marked by the square, not a C to be found by me on the upper receiver but the barrel is properly marked.

    Colt 14.5 Upper

    Posted by Louis McCotter on 21st Mar 2017

    I am very happy with the costumer service at Arms Unlimited. The staff was patient and helpful in all of the questions that I asked. The price of the Colt 14.5 lower was a great price and will do business with them in the future.
