Daniel Defense | DD4 M4A1 RIII | .223/5.56 | 14.5″ Pinned

The Daniel Defense DD4 M4A1 RIII is a semi-automatic AR-style rifle built around a purpose-driven M4A1 platform. It ships configured with a 14.5″ pinned barrel that results in a 16″ overall length and accepts a 32-round Daniel Defense magazine. This configuration is suitable for sustained range work and competition formats that favor a compact, control-oriented AR configuration. A good optic pairing under $1,000 is the Vortex Strike Eagle 1-6×24 for fast target acquisition and close-to-midrange versatility.
