Cobalt Kinetics CK-Pro URG 5.56x45mm NATO 16" Built Upper Receiver - Black Cerakote

The Cobalt Kinetics CK-Pro URG (Upper Receiver Group) is a complete, expertly built upper assembly for the AR-15 platform. Chambered in 5.56x45mm NATO with a 16" barrel and finished in Black Cerakote, the URG is designed to give end users a turn-key upgrade path onto a Mil-Spec lower receiver - bringing the same performance edge Cobalt Kinetics builds into their complete rifles onto your existing AR build.

Every CK-Pro URG is expertly assembled by Cobalt Kinetics' gunsmith staff and test-fired for function before leaving the shop, so the upper arrives ready to install and run. The 16" barrel length in this URG is well-suited for duty-length rifle builds, balancing maneuverability with effective ballistic performance out of the 5.56 NATO chambering.

Backed by Cobalt Kinetics' LIFETIME warranty, this URG is the upper receiver group only - a compatible AR-15 lower receiver (sold separately) is required to complete the build. This listing is for the 5.56x45mm NATO 16" Black Cerakote configuration (CKPROURG55616BBLK).
