Next-Generation Fighting Rifle: Daniel Defense DD4 RIII

The Daniel Defense DD4 RIII is a fully ambidextrous AR-15 platform built for shooters demanding exceptional durability, reliability, and adaptability. Chambered in 5.56 NATO/.223 Remington, the DD4 RIII features a 16-inch cold hammer-forged barrel, the advanced RIS III M-LOK rail system, and fully ambidextrous controls for maximum versatility in defensive, duty, training, and recreational applications.

Cold Hammer-Forged Barrel

At the heart of the DD4 RIII is a 16-inch cold hammer-forged 4150 Chrome Moly Vanadium barrel. This manufacturing process increases barrel durability, consistency, and longevity while maintaining the accuracy standards Daniel Defense is known for.

Advanced RIS III Rail System

The 12.5-inch RIS III M-LOK handguard provides a rigid and lightweight platform for mounting lights, lasers, grips, bipods, and other mission-essential accessories. Its free-floating design helps maximize accuracy while maintaining excellent strength and durability.

Fully Ambidextrous Controls

Designed for both right- and left-handed shooters, the DD4 RIII features a fully ambidextrous lower receiver that enhances weapon manipulation and operational flexibility under any conditions.

Mid-Length Gas System

The mid-length gas system delivers smoother cycling, reduced felt recoil, and less wear on internal components compared to traditional carbine-length systems, helping improve reliability and shooter comfort.

Battle-Proven Reliability

Built to Daniel Defense's exacting standards, the DD4 RIII offers dependable performance in demanding environments while maintaining lightweight handling characteristics suitable for extended use.

Premium Daniel Defense Furniture

The rifle comes equipped with a Daniel Defense pistol grip and Daniel Defense adjustable stock, providing enhanced ergonomics, control, and comfort during training or field use.

Flash Suppressor Equipped

A factory-installed flash suppressor helps reduce visible muzzle flash, preserving shooter vision in low-light environments while maintaining the rifle's compact handling characteristics.
