Built as a complete lower receiver assembly, this setup is intended for shooters assembling an AR-15/M16 platform with a mil-spec M4 stock already in place. It combines 7075 T6 machined aluminum forgings with hardcoat anodizing and includes a BCMA mil-spec receiver extension, staked M4 lock nut, QD end plate, and USGI H buffer. The lower is configured with a low shelf for RDIAS installation and Accuwedge use, plus an un-notched hammer compatible with 9mm use. Fire controls are marked SAFE and SEMI, making it a straightforward foundation for a serious rifle build where the listed components and compatibility matter.
