Daniel Defense DD4 RIII Upper 16in Barrel FDE Mid Length Gas M-LOK RIS

The Daniel Defense DD4 RIII Complete Upper Receiver 16" Barrel FDE delivers the longest barrel option in the RIII lineup for serious shooters, combining a 16 inch Chrome Moly Vanadium steel cold hammer forged government profile barrel with a mid-length gas system for a smoother recoil impulse and enhanced accuracy in popular shooting sports and tactical defensive scenarios. This upper features a 12.5 inch lightweight RIS III rail that free-floats the barrel, uses M-LOK attachment for reduced weight, and showcases an ambidextrous Grip-N-Rip Charging Handle paired with an M16 Profile bolt carrier group, all housed in a Mil-Spec 7075-T6 aluminum upper with indexing marks and M4 feed ramps. The barrel is chrome lined, Mil-Spec heavy phosphate coated and HP/MPI tested, while the gas block is pinned low profile CNC machined from 4140 hardened steel to ensure reliable mid-length direct impingement operation. Finishing touches include a Daniel Defense Flash Suppressor, a black or FDE Rail finish, and robust staking on the gas key, resulting in a precise, modular platform ideal for precision work, tactical training, and field engagements.
