Dan Complete Lower Receiver Group

The Daniel Defense Complete Lower Receiver Group is a fully assembled, ready-to-pair lower for builders and shooters who want mil-spec reliability backed by DD's reputation for precision manufacturing. This is the foundation of your AR platform rifle—the serialized part that matters legally—and it arrives as a complete, functioning unit. You get a properly assembled lower receiver, buffer system, receiver extension with stock adjustability, buttstock, and pistol grip in one box, eliminating the guesswork of sourcing compatible components and the time spent on assembly.

The lower itself is machined from 7075-T6 aluminum and finished with Type III hard coat anodization, a military-grade process that builds a hard, durable surface resistant to corrosion and everyday wear. Daniel Defense enhanced the design with a flared magazine well for smoother mag changes under stress and added a QD swivel attachment point on the rear receiver—thoughtful details that make this receiver practical, not just spec-compliant. Everything is made in the USA.

The included H buffer reduces felt recoil and helps ensure smooth operation across your intended use. The receiver extension features six positions of adjustability, machined from mil-spec 7075-T6 aluminum, so you can dial in a length of pull that fits your frame and shooting style. The buttstock and pistol grip are molded from glass-filled polymer with soft-touch overmolding—tough, controllable, and comfortable whether you're running gloves or shooting in shirtsleeves.

If you're assembling an AR or upgrading an existing rifle, a complete lower receiver group lets you move faster and focus on choosing your upper. Daniel Defense's engineering and build quality mean you're starting with a solid foundation.
