Daniel Defense DDM4 SB-19 Pistol w/Optic 5.56NATO 10.3" 32+1

The Daniel Defense DDM4 SB-19 w/ SLx Optic AR Pistol delivers premium Daniel Defense performance with upgraded features designed for personal defense, tactical applications, and duty use. Equipped with the Primary Arms SLx 1X MicroPrism, this compact AR pistol offers rapid target acquisition, enhanced accuracy, and dependable close-quarters performance in a rugged, lightweight platform. Built around a durable 10.3-inch barrel and the Daniel Defense MFR 9.5 M-LOK rail system, the DDM4 SB-19 provides exceptional maneuverability, reliability, and versatility. The free-floating M-LOK handguard supports a wide range of accessories, muzzle devices, and suppressor setups, making it an ideal choice for home defense, range use, and professional applications. As a pistol-configured firearm, the SB-19 is classified as an AR pistol rather than a short-barreled rifle (SBR), eliminating the need for ATF tax stamp registration or additional approval requirements.

The platform also features the fully adjustable Maxim PDW Pistol Stabilizing Brace for improved control, comfort, and compact storage. The DDM4 SB-19 comes factory-equipped with the Primary Arms SLx 1X MicroPrism with Red Illuminated ACSS Cyclops Gen 2 Reticle, providing a crisp illuminated reticle engineered for fast sight alignment and reliable performance in varying lighting conditions. Additional premium features include the independently ambidextrous GRIP-N-RIP charging handle for left- and right-handed shooters, along with the ergonomic Daniel Defense pistol grip featuring an integral trigger guard and soft-touch overmolding for enhanced comfort and control.
