The Daniel Defense DDM4ISR Upper Receiver Group is optimized for the .300 Blackout cartridge. Built around a 9”, Cold Hammer Forged barrel that is fluted along with a target crown and a standard pistol length gas system, this versatile, high-performance URG accurately delivers both subsonic and supersonic projectiles downrange with unrelenting reliability. Because the suppressor is an integral part of the barrel, it is ready for service right out of the box. There’s no attaching a suppressor and wondering if it’s mounted correctly and/or properly aligned. There’s no re-zeroing for suppressed vs. unsuppressed fire.
