AR-15 mil-spec Lower Parts Kit
Description
The CMMG Mk4 is a stripped AR-15 lower receiver, the part that houses the fire control group and serves as the foundation for a complete firearm build. It is intended for semi-automatic AR-15 builders working with 223 Remington and 5.56x45mm NATO chambered uppers.
The receiver is machined from forged 7075-T6 aluminum and finished in black Cerakote. It is designed to accept a standard mil-spec Lower Parts Kit, so the trigger, hammer, safety selector and related components are installed separately.
The Mk4 is listed as a stripped lower, so the buyer assembles it with a mil-spec Lower Parts Kit and any other desired components. Cerakote finish options are available in additional colors.
