Colt LE6921EPR Upper Reciever Kit

A true shot is wasted if the upper cannot hold it.

This 14.5-inch upper is chambered in 223 Rem and 5.56 NATO for AR rifles that need both handling and staying power.

Performance Under Pressure: The 14.5-inch barrel gives you control and hit certainty when the target is moving and the rifle is already in your shoulder.

Durability and Reliability: Precision-manufactured components and a black finish are built for repeated fire, not a single range trip.

Friction Removal: It fits AR rifles as an upper assembly, so you spend the hour shooting, not matching stray parts.

Identity Signal: A black Colt 5.56 NATO upper on an AR lower reads as a working gun, not a mixed experiment.

Proof and Credibility: Precise manufacturing and durable construction are why this upper is meant for demanding use.

Zero it, then demand the same point of impact the next time you press.
