    Colt 14.5 inch Upper Receiver Assembly

    Posted by Butchjones on 8th Feb 2021

    Opened the package and the upper came packed inside a rifle box, no manual, no barrel cap, and a Magpul MBUIS rear sight was included instead of the Matech shown in website photo. $35.00 Magpul sight VS a $ 75.00 MaTech sight, feel like I got molested without a kiss. Update your photo's on your Webpage!
