The Colt EPR Complete Upper Kit (brand part no. LE6921EPR-CK) is a factory Colt upper built around the Enhanced Patrol Rifle configuration, chambered in .223 Rem/5.56 NATO with a 14.5-inch barrel and finished in black. Colt’s precise manufacturing and durable build quality carry through this upper the same way they do across the brand’s law enforcement and military-pattern carbines, giving builders genuine Colt fit and function on a personal lower without buying a complete rifle. A 1:7 twist rate stabilizes the full range of common 5.56 bullet weights.
