Cobalt Kinetics CK-Pro URG 7.5" Upper Receiver Group 5.56x45mm NATO - FDE Cerakote

The Cobalt Kinetics CK-Pro URG (Upper Receiver Group) is a complete drop-on upper chambered in 5.56x45mm NATO, designed to bring the styling and performance of Cobalt Kinetics' Pro-series rifles to any standard AR-15 lower.

At its core is a compact 7.5" barrel configured for close-quarters work and short-barreled rifle (SBR) builds, delivering the maneuverability of a short platform without sacrificing the reliability of the 5.56 NATO cartridge. The complete upper assembly is finished across the receiver and barrel components in a corrosion-resistant Flat Dark Earth (FDE) Cerakote.

Designed as an upgrade path for owners looking to bring Pro-series performance to an existing AR-15 lower, the CK-Pro URG is engineered to Cobalt Kinetics' standards for fit, finish, and function. This listing is for the complete upper receiver group only; the lower receiver is not included.
