COBALT CK-PRO-URG-675-S-BLK STRIPPD URG 6.75 BLK

The COBALT CK-PRO-URG-675-S-BLK Stripped Upper Receiver Group 6.75 Black is purpose-built for operators and serious shooters constructing precision AR platforms from the ground up. This stripped upper receiver component provides the foundation for a complete custom rifle build, offering the modularity and control that discerning gunsmiths and builders demand when assembling a rifle tailored to specific mission requirements or range applications.

The 6.75-inch configuration delivers a compact profile well-suited for close-quarters work, vehicle operations, or confined spaces where maneuverability is critical. As a stripped receiver, this upper comes without integrated forward assist, dust cover, or charging handle, allowing builders to specify exactly which components best match their intended use case—whether that means a lightweight competitive build, a duty rifle configuration, or a specialized operator platform. The black finish resists corrosion during both storage and field deployment, and the precision machining ensures reliable indexing with compatible lower receiver assemblies and bolt carriers.

This component is engineered for buyers who understand the importance of parts-level quality control and who value the ability to hand-select every element of their rifle. Cobalt Kinetics' CK-PRO-URG-675-S-BLK upper receiver group suits precision shooters, tactical riflemen, gunsmiths, and builders who refuse compromise on material integrity or machining tolerances. The stripped configuration makes it ideal for law enforcement armorer builds, military-adjacent training platforms, and civilian precision builds where component traceability and verified material specifications matter.
