Cobalt Kinetics CK-Pro AR-15 9.8" M-LOK Black Receiver Set

The Cobalt Kinetics CK-Pro Receiver Set is a premium AR-15 build platform built around Cobalt Kinetics' signature non-rotating upper receiver design, secured by 8 TORX screws for outstanding return-to-zero performance. This 9.8" variant pairs an aluminum upper and lower with a 9.8" M-LOK handguard in a clean black finish, ideal for a compact carbine or mid-length build.

The CK-Pro line is engineered around the 5.56x45mm NATO cartridge and follows the standard AR-15 architecture, giving builders a high-end foundation. The set ships with everything required to assemble a complete upper and lower pair: upper receiver, lower receiver, M-LOK handguard, ejection port assembly, forward assist assembly, mounting screws, jam nut, and jam nut installation tool.

Manufactured from aluminum and backed by Cobalt Kinetics' lifetime warranty, the 9.8" CK-Pro Receiver Set delivers the precise fit and finish the platform is known for and provides a strong, rigid foundation for a custom AR-15 build.
