Cobalt Kinetics CK-Pro 16" M-LOK Black Receiver Set

The Cobalt Kinetics CK-Pro Receiver Set provides the foundation for a premium AR-15 platform build. Machined from 7075 T6 billet aluminum and finished in hardcoat anodized black, this receiver set showcases Cobalt Kinetics' proprietary non-rotating upper receiver design that uses 8 TORX screws to lock the handguard down with exceptional rigidity and a return-to-zero hold.

Designed around the 5.56 NATO platform, the CK-Pro pairs a billet upper and lower with a slim 16" M-LOK handguard that offers ample accessory real estate while keeping the overall package well-balanced. The non-rotating handguard interface eliminates the play and shift common to traditional clamp-on designs, giving builders a stable platform for optics and accessories.

Each CK-Pro Receiver Set ships with:

• Billet upper receiver with non-rotating handguard interface
• Billet lower receiver (serialized)
• 16" M-LOK handguard
• Ejection port assembly
• Forward assist assembly
• Necessary mounting screws
• Jam nut
• Jam nut installation tool
