Colt M4/AR15 Receiver Extension Castle Nut November 19, 2018
Reviewer: Marty from West Covina , CA United States  
AU sells authentic Colt parts and the Colt M4  Receiver Extension Castle nut is no exception.  Castle nut was brand new. The exceptional things about AU are their customer service, best prices on Colt products, fast shipping and no tax!
