Cobalt Kinetics CK-Pro 11.8" 5.56x45mm NATO Flat Dark Earth Cerakote Receiver Set

The Cobalt Kinetics CK-Pro Receiver Set is a precision-machined aluminum upper and lower set finished in a durable Flat Dark Earth Cerakote. Purpose-built as the foundation of the CK-Pro rifle platform, this set pairs an 11.8" handguard with the matching upper and lower receivers and is rated for 5.56x45mm NATO.

Cobalt Kinetics machines the upper receiver, lower receiver, and handguard from aluminum for a rigid platform with clean lines and integrated rail space. The matching Flat Dark Earth Cerakote finish provides corrosion resistance and a uniform, low-visibility appearance across the entire set.

Every CK-Pro Receiver Set ships complete with the upper receiver, lower receiver, handguard, ejection port assembly, forward assist assembly, the necessary mounting screws, a jam nut, and the jam nut installation tool. Everything needed to begin a CK-Pro build. Backed by Cobalt Kinetics' lifetime warranty.
