The Daniel Defense DD4 RIII 5.56 AR-15 rifle is purpose-built for shooters who demand a direct-impingement platform that balances reliability, accuracy, and modularity. Chambered in 5.56 NATO (and compatible with .223 Remington), this 16-inch mid-length gas system rifle delivers the handling characteristics serious shooters expect—fast enough for tactical work, handy enough for hunting, and accurate enough for extended range sessions. Daniel Defense's reputation rests on meticulous attention to detail, and the DD4 RIII proves it in every component, from the chrome-lined barrel to the ambidextrous controls.
The 16-inch 4150 CRMOV chrome-lined barrel features a 1:7 twist rate built for modern ammunition performance and wears a extended flash hider threaded at 1/2x28. The upper and lower receivers are fully ambidextrous—charging handle, mag release, and safety controls all work from either side, eliminating the limitations of right-hand-only rifles. The heart of the gun is a mil-spec tested, chrome-lined bolt carrier group and M16 profile carrier that cycles reliably across a wide range of ammunition and suppressor configurations.
What sets the DD4 RIII apart is the 12.5-inch M-Lok RIS III free-float handguard. Unlike standard quad rails, this aluminum platform is genuinely lighter and easier to control, features integrated M-Lok slots for optics and accessories, and floats away from the barrel for consistent accuracy. The six-position adjustable stock and H buffer deliver a smooth recoil impulse, while the overall length ranges from 32.25 to 35.875 inches—compact enough to maneuver in tight spaces but long enough for a solid sight picture and controls. At 6.52 pounds unloaded, the DD4 RIII sits in the sweet spot: light enough to carry all day, substantial enough to shoot with authority.
This rifle ships with a 32-round magazine capacity and the reliability Daniel Defense is known for. Whether you're building a do-it-all rifle for hunting, defensive use, or the range, the DD4 RIII is a proven platform that adapts to your mission.
