Cobalt Kinetics CK-Pro AR-15 10.8" M-LOK Black Cerakote Receiver Set

The Cobalt Kinetics CK-Pro Receiver Set brings the CK-Pro's flagship AR-platform architecture to your custom build. This set pairs a CK-Pro upper receiver with a CK-Pro lower receiver and a 10.8" free-float M-LOK handguard, all finished in Black Cerakote. Both the upper and lower are CNC-machined from 7075 T6 aluminum, while the handguard is cut from 6061 aluminum for an optimized strength-to-weight ratio. The set is built around the 5.56 NATO chambering and is configured as the foundation for the CK-Pro rifle platform.

The CK-Pro upper features the line's distinctive receiver geometry. The M-LOK handguard provides a versatile, lightweight mounting surface for accessories. Backed by Cobalt Kinetics' lifetime warranty, the CK-Pro Receiver Set is intended for end users who want to assemble a top-tier custom AR-pattern rifle.

Note: This listing includes the upper receiver, lower receiver, and handguard only. Barrel, bolt carrier group, charging handle, lower parts kit, and stock or pistol brace are sold separately.
