Cobalt Kinetics CK PRO URG 5.56 NATO 11.5" AR-15 Upper Receiver

Cobalt Kinetics CK-Pro Urg Upper Features The Cobalt Kinetics CK-Pro Urg upper is machined to accept a standard AR-15 lower giving builders a drop-in option for completing a carbine or pistol-length rifle in 5.56x45mm NATO. The 11.5 barrel keeps the overall package short and maneuverable which matters in vehicles doorways and other confined environments where a full-length barrel becomes a liability. Cobalt Kinetics builds its reputation on competition-grade AR components so the fit and finish on this upper reflect that same attention to tolerance and function. The black Cerakote receiver finish adds a layer of corrosion and wear resistance beyond raw metal. Because this is sold as an upper only it drops onto any mil-spec AR-15 lower receiver letting a shooter repurpose an existing lower or complete a new build around it. The 11.5 barrel length places this upper in pistol or SBR territory depending on the host configuration and local regulations. Builders looking to assemble a dedicated short-barrel rifle or AR pistol get a proven receiver and barrel combination without starting from raw parts. This upper is a practical choice for anyone assembling a compact purpose-built AR-15 platform for defensive or range use.
