Daniel Defense DD4 RIII AR-15 Complete Upper Receiver 5.56x45mm 16" Barrel Mil-Spec+

Overview

The Daniel Defense DD4 RIII complete upper receiver assembly is chambered in 5.56x45mm and features a 16-inch cold hammer forged government profile barrel. Built for the AR-15 platform, this assembly includes a mid-length gas system, which provides a smoother recoil impulse for improved accuracy during rapid fire. It is equipped with a pinned low-profile gas block and a GRIP-N-RIP charging handle. The upper features a 12.5-inch lightweight RIS III rail system. Modeled after the RIS II developed for SOCOM, the rail utilizes M-LOK attachment points to reduce weight while maintaining the ability to mount accessories like M203 grenade launchers. This complete upper receiver group also comes standard with an M16 profile bolt carrier group. It is finished in anodized black.
