The DPMS AR-15 B5 Lower (brand part no. DP51655129036) is a complete, serialized AR-15 lower receiver assembly machined from 7075-T6 aluminum forgings, giving builders a ready-to-run, multi-caliber-compatible foundation for a custom rifle. DPMS hard-coat anodizes the receiver to MIL-A-8625F Type III Class 2 spec, fits a B5 Systems Bravo stock and black B5 grip, and finishes the trigger with the DPMS Panther Polished Trigger (PPT) treatment.
