Cobalt Kinetics CK-Pro AR-15 6.75" M-LOK FDE Receiver Set

The Cobalt Kinetics CK-Pro Receiver Set is a premium, turn-key foundation for a high-performance AR-15 rifle build. Machined from aluminum and finished in Flat Dark Earth (FDE), this matched upper and lower set delivers the brand's signature look and a rigid mounting interface right out of the box.

Every CK-Pro receiver set ships with the matched upper, lower, 6.75" M-LOK handguard, ejection port assembly, forward assist assembly, the necessary mounting screws, the jam nut, and the jam nut installation tool. Cobalt Kinetics' proprietary design language carries through every component, giving your build a clean, uniform appearance.

The M-LOK handguard offers modern accessory compatibility for lights, lasers, grips, and bipods, and the matched FDE anodized finish carries across every part. Whether you are assembling a competition rifle, a defensive carbine, or a precision platform, the CK-Pro set gives you a serialized, finished starting point to build on with your choice of barrel, bolt carrier group, lower parts kit, stock, and accessories.

As a serialized receiver set, this item transfers through a standard firearms dealer.
