Semi-Automatic Rifle DDM4 M4A1 RIII 14.5" / Caliber 5.56 mm NATO Daniel Defense®

The DDM4 M4A1 RIII from Daniel Defense^® is engineered for both right- and left-handed shooters, featuring a fully ambidextrous lower receiver. With controls that can be accessed without releasing your firing grip, this rifle ensures optimal control in high-pressure situations. The GRIP-N-RIP charging handle is also ambidextrous, enhancing operational flexibility.

Exceptional Control and Maneuverability

Experience enhanced control and unmatched agility with this lightweight, yet powerful rifle. Regardless of your dominant hand, the ambidextrous controls for the bolt catch, magazine release, and safety selector allow seamless operation—perfect for tactical, defensive, or sporting use.

Proven Six-Bolt Attachment System

The DDM4 M4A1 RIII utilizes Daniel Defense’s patented six-bolt Bolt-Up^® system, originally developed for the RIS II rail. This battle-proven design delivers rock-solid stability—robust enough to handle the recoil of a mounted M203 grenade launcher.

Ready for Mission-Specific Add-Ons

The rifle's modular two-piece rail design allows easy removal of the lower rail section for quick M203 launcher installation. This flexibility makes it suitable for both military-style setups and civilian use.

Modernized 12.5" RIS III Rail

The traditional RIS II Picatinny rail has been upgraded to a 12.5" RIS III rail featuring the M-LOK interface. The result? A lighter, more ergonomic platform without compromising strength or mounting capabilities—including support for the M203 grenade launcher.

Cold-Hammer Forged Barrel

At the core is a 14.5" cold-hammer forged barrel with a permanently pinned Daniel Defense Flash Suppressor. This enhances both durability and muzzle control. The rifle also includes a Daniel Defense ergonomic pistol grip and buttstock for increased shooter comfort.

Chambered in 5.56 mm NATO

The rifle's 5.56 mm NATO chamber offers excellent compatibility with widely available ammunition. Its overall design ensures comfort, adaptability, and reliable performance in any conditions. And as with all Daniel Defense firearms, it’s proudly made in the USA.
