Battle Arms Development WH556-LR-ODG Workhorse Lower Receiver OD Green Anodized for AR15/M16/M4

The Battle Arms Development WH556-LR-ODG Workhorse Lower Receiver in OD Green anodized finish is purpose-built for shooters and operators who demand a reliable foundation for their AR15, M16, or M4 platform rifle. This lower receiver serves as the federally regulated serialized component and primary structural backbone of any modern piston or direct impingement carbine system.

Machined from aerospace-grade aluminum and finished in Mil-Spec OD Green anodizing, the Workhorse lower receiver resists corrosion, saltwater exposure, and UV degradation in demanding outdoor environments. The anodized coating provides a durable hard-coat finish that withstands repeated cycling, cleaning solvents, and field handling without compromising structural integrity or aesthetic appeal.

Battle Arms Development's engineering delivers tight tolerances on critical engagement surfaces, ensuring reliable upper-to-lower fit and repeatability across multiple upper assemblies without excessive play or binding. The OD Green color matches standard military and tactical gear palettes, making it an ideal choice for cohesive rifle builds or replacement components in existing arsenals. The WH556-LR-ODG lower receiver is compatible with all standard AR15 upper receivers and components.
