This complete lower parts kit is intended for building or refreshing an AR-15 lower with the core components needed for assembly, including a QMS trigger and the small parts that support controls, detents, and pins. It is suited to hunters and shooters who want a straightforward parts package for a rifle setup without piecing together each item separately. The kit is offered with or without a grip, giving some flexibility depending on the build. Made by ALG Defense, it provides a practical foundation for a clean, functional lower receiver build.
