Built on the AR-15 platform, the DDM4 PDW pairs a compact 7-inch chrome-moly-vanadium steel barrel with a pistol-length gas system to optimize reliability with .300 BLK. The barrel is cold hammer forged with Daniel Defense’s S2W profile for durability, a 1:7 twist for typical .300 BLK loadings, and 5/8x24 threads.
The free-float Daniel Defense MFR XL 6.0 M-LOK handguard is made from 6061-T6 aluminum and includes an integral front handstop. A full-length Picatinny top rail spans the receiver and handguard for uninterrupted mounting space. The upper and lower receivers are 7075-T6 forged aluminum with a hard-anodized finish, and the rifle uses a semi-automatic, direct impingement operating system.
A Maxim Defense CQB Gen 7 telescoping PDW stock delivers a short overall package with an approximate length of pull from 9 to 13.5 inches. The two-rod design with a push-button latch and skeletonized buttplate keeps the rear profile slim. Overall length is approximately 20.75 to 24.75 inches, and unloaded weight is about 5 lb 11 oz. A textured polymer pistol grip with a beavertail provides a secure hold.
The installed Dead Air KeyMount/KeyMo muzzle brake enables quick-attach use of KeyMo-compatible suppressors and comes with the correct 5/8x24 shim kit. Capacity is 30+1 in .300 AAC Blackout, and this NFA Item SBR includes three Magpul PMAG 300 BLK magazines and a Daniel Defense hard case.
