The M4E1 Lower Receiver delivers billet aesthetics in a forged package. This custom-designed enhanced forging is machined from 7075-T6 Aluminum and compatible with all mil-spec AR15 parts. Aside from the visual upgrades, this custom-engineered design provides features that challenge much more expensive billet options and simplify the assembly process for the at-home builder.
