Cobalt Kinetics CK-Pro URG Stripped 5.56 NATO 10.8" M-Lok Upper Receiver - FDE

The Cobalt Kinetics CK-Pro URG stripped upper receiver group gives builders a premium foundation for a hard-use 5.56x45mm NATO AR-15. Machined to Cobalt Kinetics' exacting standards and finished in a rugged Flat Dark Earth Cerakote, this stripped URG ships without a bolt carrier group, charging handle, or barrel so you can configure it to your exact build.

The integrated handguard measures 10.8 inches and is machined from 6061 aluminum in Cobalt Kinetics' signature 7-sided profile with full M-Lok compatibility for accessories. The URG (Upper Receiver Group) accepts standard AR-15 barrels and components chambered in 5.56 NATO, making it a versatile starting point for duty, competition, or defensive rifles.

This is the stripped configuration: the upper receiver and 10.8" handguard are included; BCG, charging handle, and barrel are not included and must be sourced separately. Backed by Cobalt Kinetics' lifetime warranty, the CK-Pro URG is engineered for serious hard-use applications.
