Overview
The DANIEL DEFENSE DDM4 PDW in 300 Blackout delivers a compact, high-performance platform optimized for close-quarters engagement and personal defense. Engineered with Daniel Defense’s commitment to robust construction and precision manufacturing, this AR pistol provides an agile solution without compromising terminal ballistics or reliability. Its design prioritizes operational efficiency in confined environments while maintaining the consistent performance expected from the DDM4 series.
Key Features
Optimized Ballistic Integration
The 7-inch cold hammer forged barrel, specifically chambered for 300 Blackout, ensures efficient projectile acceleration and consistent accuracy. The 1:7 twist rate effectively stabilizes a wide range of bullet weights, from subsonic to supersonic loads, mitigating the need for specialized barrel configurations.
Advanced Gas System
A precisely tuned pistol-length gas system, paired with a low-profile gas block machined from 4140 hardened steel, guarantees reliable cycling across varying ammunition types. This system is designed to provide consistent bolt carrier group velocity, enhancing operational reliability and reducing component wear.
Robust Receiver Construction
Both the upper and lower receivers are CNC machined from 7075-T6 aluminum, finished with a Type III hard coat anodize for superior corrosion and abrasion resistance. The mil-spec upper includes indexing marks and M4 feed ramps to optimize feeding. The lower receiver features an enhanced flared magazine well for expedited reloads and an integrated rear QD swivel attachment point for sling integration.
Ergonomic Control Interface
Equipped with Daniel Defense’s MFR XL 6.0 M-LOK handguard, the DDM4 PDW allows for direct attachment of accessories, maintaining a sleek, low-profile form factor. The Daniel Defense pistol grip features soft-touch overmolding for enhanced weapon manipulation and control.
Integrated Stability
A robust Pistol Stabilizing Brace is integrated, providing enhanced stability and control, thereby improving the utility of the platform in dynamic shooting scenarios.
