The Cobalt Kinetics CK-Pro URG is a precision-built complete upper receiver group engineered for the AR-15 platform. Chambered in 5.56x45mm NATO and finished in a durable Black Cerakote, this URG combines Cobalt Kinetics' refined CK-Pro platform with their Upper Receiver Group configuration for shooters building or upgrading a duty-grade rifle around a compatible lower.

Featuring a 13.7" barrel, the CK-Pro URG delivers a versatile profile that pairs naturally with a sound suppressor and covers a broad range of roles. The Black Cerakote coating provides corrosion resistance and a low-glare, professional appearance that holds up to hard use in the field. Like every Cobalt Kinetics upper, the CK-Pro URG is backed by the company's reputation for tight tolerances, meticulous build quality, and their lifetime warranty.

This listing is for the complete upper receiver group only and is intended to be paired with a mil-spec or compatible AR-15 lower receiver. Whether you are completing a custom build or seeking a premium upgrade to an existing platform, the Cobalt Kinetics CK-Pro URG offers a refined, feature-rich foundation for a serious 5.56 NATO rifle.
