Daniel Defense ISR-Black

The Daniel Defense DDM4 ISR is an advanced AR15-style rifle designed for the 300 Blackout caliber. It includes a fully integrated suppressor, a 15-inch KeyMod handguard, and a pistol-length gas system. The combination of these features makes the rifle efficient, balanced, and easy to handle in different shooting conditions.

The DDM4ISR is now offered in a clean and modern black finish. It weighs just 7.75 pounds, making it lightweight for an integrally suppressed platform. The rifle is built to deliver stable and accurate performance with both subsonic and supersonic ammunition. This makes it suitable for shooters who want reliability and smooth operation straight out of the box.

Daniel Defense designed the rifle with a 1913 Picatinny rail on top. It also features KeyMod slots at the 3, 6, and 9 o’clock positions. These mounting points allow users to attach lights, grips, and other accessories with ease. The extended handguard provides better control. The Daniel Defense buttstock and pistol grip also improve comfort, especially during longer shooting sessions.

The DDM4ISR comes in Black, and it is also available in Green and Milspec+ color options for users who prefer different finishes.
