The Daniel Defense DDM4ISR (Integrally Suppressed Rifle) 300 joins our family of precision-crafted M4 Rifles. ï¿½The 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. ï¿½While the rifle utilizes a 10.3ï¿½ barrel, it is not classified as an SBR (Short-Barreled Rifle) because the suppressor is permanently attached. ï¿½The DDM4ISR 300ï¿½s sound suppressor is threaded and welded to the proprietary ISR Integrated Gas Block, bringing the barrel length to 16.145ï¿½. ï¿½While the rifle is at the 16ï¿½ legal limit, the ISRï¿½s integrated suppressor will require an NFA tax stamp. ï¿½ This rifle also comes with the newly designed, rugged and comfortable Daniel Defense Buttstock and Pistol Grip.
Using the tool provided, the ISRï¿½s baffle core is removable for cleaning. ï¿½With the inclusion of the Daniel Defense Modular Float Rail (MFR) 12.0, it provides the shooter with the ultimate in modular adaptability. ï¿½This rifle can be run ï¿½slickï¿½ with an uninterrupted top rail that runs the length of the tube. ï¿½In addition, the 3ï¿½ Modular Picatinny Rail sections allow the end user to customize the rail set up.
This firearm is a regulated item by the National Firearms Act (NFA). Please check with your local and state municipalities for any further regulatory requirements. It is the buyerï¿½s responsibility to make sure they comply with all NFA rules and applicable laws.
