Lee Thompson, the engineer behind Daniel Defense's newest addition to its M4 family, explains that the company has integrated key components into one package with its DDM4ISR (Integrally Suppressed Rifle). In effect, this eliminates the need for two separate tax stamps. This rifle, in .300 BLK, utilizes a 10.3-inch barrel, but is not classified as an SBR (Short Barreled Rifle) because the suppressor is permanently attached. The DDM4ISR 300’s sound suppressor is threaded and welded to the proprietary ISR Integrated Gas Block, bringing the barrel length to 16.145-inches--just over the 16-inch legal limit, the ISR’s integrated suppressor will require an NFA tax stamp.

The ISR’s baffle core is removable for cleaning (tool provided), and the Daniel Defense Modular Float Rail (MFR) 12.0 gives 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, and the 3-inch Modular Picatinny Rail sections allow the end user to customize the rail set up.
