    Colt 11.5 inch M4 Commando Upper Receiver Assembly

    The Colt 11.5 full upper was shipped in a full Colt Carbine CR6933 box with no padding. Upon receipt the front post sight had penetrated the box and was sticking out. No damage and there was a outer plastic bag to prevent oil staining which USPS doesn’t like to see. All in all I was quite pleased with the product and would recommend. More detail to packaging for shipment would be appreciated.

    I know it’s been in use for only for aprox 26 years , but the moment it came into service was a instant favorite for a chosen and lucky few , this modern 9633 is solid in all sense of the word . I’m glad I found one available in A.U.
