About this product

The Daniel Defense DD4 M4A1 RIII is a semi-automatic AR-style rifle built around a 14.5 inch cold hammer-forged M4-profile barrel and a 12.5 inch RIS III rail featuring M-LOK attachment points. The design emphasizes ambidextrous controls, a GRIP-N-RIP ambidextrous charging handle, and a mid-length gas system intended to deliver smooth, reliable cycling. Construction uses CNC-machined 7075-T6 aluminum receivers with hard-coat anodize finishes and Daniel Defense furniture for a durable, service-ready package.
