Cobalt Kinetics CK-Pro Urg Stripped Upper Features The Cobalt Kinetics CK-Pro Urg stripped upper receiver is machined from aluminum and designed to bring the same performance characteristics found in Cobalt Kinetics complete rifle platforms to an existing AR build. At 10.80 inches the upper gives a builder a solid foundation on which to mount a barrel bolt carrier group and handguard of their choosing. A Black Cerakote finish protects the aluminum from corrosion and wear giving the receiver a durable long lasting surface that matches most modern AR builds. Because it ships stripped the builder retains full control over the internal components and configuration of the completed upper. Cobalt Kinetics gunsmith staff expertly builds and test fires every CK-Pro upper before it leaves the shop a level of quality control that goes beyond typical mass produced uppers. This hands on approach is aimed at AR owners looking to upgrade their current rifle to the performance edge found in Cobalt Kinetics fully assembled platforms. A stripped upper configuration also allows a builder to select their own barrel length gas system and handguard to suit a specific use case whether competition hunting or duty. The Cobalt Kinetics CK-Pro Urg Stripped Upper is for sale at GrabAGun for AR builders who want a premium gunsmith verified foundation for their next build.
