Finished in a distinctive Cobalt color, the DDM4 PDW combines premium materials with a refined, modern appearance.

Designed for home defense, personal protection, and range use, the DDM4 PDW is equipped with a Maxim Defense CQB pistol brace that allows for adjustable length and improved control. The 6-inch MFR XL free-float handguard offers a slim profile with M-LOK compatibility, providing ample space for lights, grips, and other accessories. A pistol-length gas system ensures smooth, reliable cycling, while the threaded muzzle supports suppressor or muzzle device compatibility. Built to Daniel Defense’s exacting standards, the DDM4 PDW delivers trusted performance in an ultra-compact AR platform.
