Daniel Defense has already established themselves as a first rate rifle and component manufacturer, so it was no surprise to visit their booth at SHOT Show this year and find another great design: the Daniel Defense ISR. The ISR, or Integrally Suppressed Rifle, was designed from the ground up to be one complete package, which I explain below. The official model number is DDM4ISR 300.
The Integrated Suppressor (IS)
Matt Mozak of Daniel Defense walked me through the latest, greatest DD rifle. The rifle is designed to be a weapon system, and not just a rifle with accessories added. To accomplish this, Daniel Defense developed and added their all new Integrated Suppressor (IS). The integrated suppressor is threaded, pinned and welded to the rifle’s proprietary lSR gas block, in what Mozak called a monolithic baffel. So the IS becomes a permanent part of the rifle, and not simply an interchangeable accessory. The length of the barrel and Integrated Suppressor together is 16.145”.
