Description: 
 

Factory New Carrillo Customs Inc. M4 lower receiver is a factory-assembled AR-15 component configured for multi-caliber use. Machined in the United States from 7075-T6 aluminum forging, it features a matte black Cerakote finish. The receiver bears engraved Mexican federal markings referencing the State of Jalisco on the magazine well, providing distinctive identification. Machining follows military specifications for compatibility with standard AR-15 upper receivers and related components.

The receiver assembly includes a complete lower parts kit installed at the factory, along with a buffer extension and adjustable buttstock. The selector, trigger group, takedown pins, and magazine catch are all pre-installed. The receiver is marked “Multi-Cal,” designating its intended use across various chamberings within the AR-15 platform. This M4 lower is in new condition, with uniform machining and consistent surface treatment typical of new production aluminum parts.

Included with the assembly are the internal components, trigger mechanism, safety selector, takedown pins, magazine release, and adjustable stock. The pistol grip is custom-made and engraved with the Mexican eagle design, integral to the overall configuration. All markings and engravings are applied directly to the aluminum surface during manufacturing by Carrillo Customs Inc.
