Great product April 26, 2017
Reviewer: James Foster from Pico Rivera, CA United States  
The colt 16 inch upper assembly I purchase is an excellent product. It came just as advertised and was so easy to attach to my lower receiver. The shipping did take a little longer than I hoped. Next time ill pay for the overnight delivery. Other than that I'm very pleased to have made my purchase with you guys.
