Cobalt Kinetics CK-Pro URG 13" Stripped Upper Receiver - Aluminum Black Cerakote

The Cobalt Kinetics CK-Pro URG is a stripped upper receiver built for AR-platform shooters who want the same precision-machined quality that defines Cobalt Kinetics' complete rifles. This Stripped configuration ships without a bolt carrier group, charging handle, or barrel, giving you the receiver foundation to pair with your preferred BCG, barrel, and handguard for a custom build.

The receiver is machined from aluminum and finished in a tough Black Cerakote, delivering the corrosion resistance and clean matte appearance needed for hard use in the field or on the range. At 13" overall length, it forms the core of the CK-Pro Upper Receiver Group and is designed around the 5.56x45mm NATO chambering that defines the CK-Pro series.

Whether you are upgrading an existing AR-platform rifle or laying the foundation for a new Cobalt Kinetics-inspired build, the CK-Pro URG provides the precision-machined receiver core for a high-end, duty-grade upper.
