The Cobalt Kinetics Cobalt CK-Pro-URG-675-S-CKG 6.75" URG CKG is a compact upper receiver group built for shooters who want a short, maneuverable AR-pattern top end without sacrificing quality. This assembled unit pairs a precision-machined aluminum upper with a matching handguard, offering a clean profile and smooth operation when mated to a standard AR-15 lower receiver.

With its 6.75-inch configuration, this PRO Series upper is well suited for range use, training, and building a compact rifle or pistol where overall length and balance matter. The lightweight aluminum construction helps keep the front end responsive, while the manufacturer’s attention to fit and finish supports consistent performance over time. Cobalt Kinetics is known for thoughtful engineering and refined machining, making this upper receiver group a solid foundation for a quality AR build.
