Product Features & Specifications
The DDM4ISR is our Integrally Suppressed AR15-style firearm optimized for the 300 Blackout cartridge. Built around a 9-inch 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 firearm is ready for service right out of the box. There's no attaching a suppressor, and I'd like to know if it's mounted correctly or adequately 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 can withstand extreme temperatures and harsh environments. The suppressor is also user-serviceable, so its baffle core can be easily removed for periodic cleaning to maintain peak performance. The DDM4ISR comes standard with the MFR XL 15.0 handguard, which features a continuous 1913 Picatinny rail on its top for mounting iron sights or optics and Keymod attachment points on the sides and bottom.
The independent Ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters. This rifle also comes with the ergonomic Daniel Defense Buttstock and Pistol Grip.
