The Daniel Defense DDM4ISR (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 DDM4ISR 300‚Äôs 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.
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.
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 buyer’s responsibility to make sure they comply with all NFA rules and applicable laws.
