Colt 6921 Complete Upper Receiver
Best price found with Arms Unlimited. Very Fast Shipping. Was in Sealed Factory Packaging. This is not My First Purchase from Arms Unlimited and Definately will not be my last!

Colt 14.5" upper
correction: after inspecting both bcgs again under intense lighting, i did find the most faint, barely legible MPC markings ever, on the bolts. so for my previous comment, i stand corrected. but as for all the visible bolt wear, it's not just one bolt... it's that way on the pair.

Colt 14.5" upper
i recently purchased two of these based on product description and what i received was disappointing. While both carriers have a faint etched C, neither bolt has the customary Colt "C" or MPC . Nothing at all! one bolt also also showed very heavy wear around the firing pin hole and debris up inside the gas key. Clearly, not what one expects on a Colt Upper advertised as New. Choose wisely.

Packaging
Upper was what It should be, but the packaging was pretty shorty! It came in a Colt rifle box. It was significantly damaged and the upper was just sliding around inside the box, it wasn’t damaged but I would have thought that it would have been packed with styrofoam or bubble wrap. Thanks again for your quality product!
