The Cobalt Kinetics CK-Pro Upper Receiver Group (Cobalt Kinetics part no. CKPROURG108SFDE) is a 10.8-inch stripped upper finished in flat dark earth, designed for AR-15 owners who want the same performance edge found on Cobalt Kinetics’ complete rifles without replacing their entire platform. Every CK-Pro URG is expertly built by Cobalt Kinetics’ own gunsmith staff and test-fired for function before it ships, rather than being sold as a bare, unverified receiver. Because it is sold stripped, builders retain full control over which barrel, bolt carrier group, and handguard they pair with it.
