The Daniel Defense DDM4ISR is our Integrally Suppressed Weapon System optimized for the .300 Blackout cartridge. Built around a 9”, Cold Hammer Forged barrel that is fluted along with a target crown and a standard pistol-length gas system, this versatile, high-performance rifle is the complete package, accurately delivering both subsonic and supersonic projectiles downrange with unrelenting reliability. Because the suppressor is an integral part of the barrel, this weapon system is ready for service right out of the box. There’s no attaching a suppressor and wondering if it’s mounted correctly and/or properly aligned. There’s no re-zeroing for suppressed vs. unsuppressed fire.
The DDM4ISR’s integral suppressor extends the barrel to an NFA-required 16 inches in length, so this platform is not classified as a Short Barreled Rifle (SBR) and therefore only requires a single tax stamp (for the suppressor). The suppressor’s lightweight outer tube is constructed of durable, heat-resistant metal alloys and coated with a protective high-temperature Cerakote-C finish, which is able of withstanding extreme temperatures and harsh environments. The suppressor is also user-serviceable, so its baffle core can be easily removed for periodic cleaning in order to maintain peak performance.
The DDM4ISR comes standard with Daniel Defense’s MFR XL 15.0 modular handguard, which features a continuous 1913 Picatinny rail on its top, for the mounting of iron sights or optics, and Keymod attachment points on the sides and bottom. This longer, multi-functional handguard, in conjunction with a Daniel Defense Buttstock and Pistol Grip, make the DDM4ISR as ergonomic and maneuverable as it is versatile. A resilient, attractive Daniel Defense Deep Woods Cerakote finish not only protects this weapon system from the elements, it also adds to its overall aesthetics—so while you’re sending rounds down range; you’ll also turn a few heads.

The information below comes from our Gun Caliber Dictionary and is for
general reference only. It does not describe the specifications of this
particular item.
The 300 AAC Blackout (300 BLK) was developed in 2009/2010 by Advanced Armament Corporation and approved by Sporting Arms and Ammunition Institute (SAAMI) in 2011. Based on the 223 Remington case necked up to 30-caliber, it was intended for the M4 Carbine and designed to function in standard AR15/M16 magazines. Thus converting an AR to 300 AAC Blackout requires nothing more than an upper receiver group. Dimensionally it is identical to the 300 Whisper, but the 300 Blackout is fully standardized. Supersonic and subsonic ammunition is manufactured, with a 125-grain bullet producing 2215 feet per second, while the subsonic load uses a heavier bullet at much lower velocity: 220-grain bullet at 1080 fps. Military applications are obvious; as a sporting cartridge performance is similar to the 7.62x39.
