This Daniel Defense DD4 RIII upper receiver group is a complete 5.56 NATO upper with a 14.5-inch barrel and a flat dark earth finish. Daniel Defense is well known for quality controlled, hammer-forged barrels, and the RIII rail provides plenty of room for optics, lights, and accessories. It is a good way to upgrade an existing AR-15 lower or complete a build with a proven, duty-style upper.
