Diamondback DB2228R001 DB15 Lower Receiver Multi Black

The Diamondback DB2228R001 DB15 Lower Receiver in Multi Black is a precision-machined FFL firearm component purpose-built for AR-15 platform builders and tactical professionals who demand reliability and accuracy in modular rifle construction. This lower receiver serves as the legally regulated foundation of any DB15 build, housing the trigger group, fire control components, and buffer tube assembly. Whether you're assembling a duty rifle, precision carbine, or custom tactical platform, a quality lower receiver is non-negotiable—it's the serialized foundation upon which accuracy, reliability, and compliance depend.

Diamondback's DB15 lower receiver is manufactured to exacting tolerances, engineered to accept standard AR-15 compatible fire control groups, stocks, and buffer tube assemblies. The multi-black finish provides corrosion resistance and a professional tactical appearance while withstanding field conditions and routine maintenance. The receiver's robust design accommodates full-auto-rated components, making it suitable for both semi-automatic civilian builds and law enforcement or military applications where durability under sustained use is critical. Precision drilling and mil-spec tolerances ensure that bolt carrier groups cycle smoothly and lockup remains consistently tight across thousands of rounds.

This lower receiver is ideal for gunsmiths, armorsmiths, and experienced rifle builders constructing anything from patrol carbines to precision match rifles. Law enforcement agencies, military units, and civilian shooters who standardize on the AR-15 platform will find the Diamondback DB15 lower receiver compatible with all mil-spec upper receivers, trigger groups, and furniture. Installation requires basic gunsmithing knowledge or professional assembly; proper headspacing verification and function-checking are essential before firing. As an FFL-regulated component, this lower receiver ships only to licensed dealers and must comply with all applicable federal, state, and local firearms regulations.
