DANIEL DEFENSE ISR 300 BLACKOUT (INTEGRALLY SUPPRESSED RIFLE)
The Daniel Defense DDM4 ISR-300 (Integrally Suppressed Rifle) 300 joins our family of precision-crafted M4 Rifles. The ISR takes advantage of the best characteristics of the 300BLK by integrating key components into one package, eliminating the need for two separate tax stamps. While the rifle utilizes a 10.3” barrel, it is not classified as an SBR (Short-Barreled Rifle) because the suppressor is permanently attached. The Daniel Defense DDM4 ISR-300’s sound suppressor is threaded and welded to the proprietary ISR Integrated Gas Block, bringing the barrel length to 16.145”. While the rifle is at the 16” legal limit, the ISR’s integrated suppressor will require an NFA tax stamp. This rifle also comes with the newly designed, rugged and comfortable Daniel Defense Buttstock and Pistol Grip.
Using the tool provided, the ISR’s baffle core is removable for cleaning. With the inclusion of the Daniel Defense Modular Float Rail (MFR) 12.0, it provides the shooter with the ultimate in modular adaptability. This rifle can be run “slick” with an uninterrupted top rail that runs the length of the tube. In addition, the 3” Modular Picatinny Rail sections allow the end user to customize the rail set up.
