Daniel Defense DD4 RIII 5.56mm 16″ (CA Compliant) Rifle 02-191-03270-055



Daniel Defense’s DD4 RIII takes much of its design from the DDM4, but has a reduced weight and offers even more flexibility. The DD4 RIII’s safety selector, bolt release, and charging handle are fully ambidextrous, allowing both left and right handed to operate the rifle without moving their dominate hand from the grip. The rifle is also outfitted with the exclusive RIS III rail system – an optimized version of the renowned RIS II rail that was developed by SOCOM. The RIS III rail system is lighter than the RIS II but still provides extreme durability, and multiple M-LOK attachment points allow for the installation of tactical lights/lasers, vertical grips, and other M-LOK compatible accessories. The RIS III incorporates the 6-Bolt, Bolt-Up system, an attachment that is strong enough to withstand the recoil from an M203 grenade launcher. In addition, the DD4 RIII features a full-length flattop picatinny rail for optics and iron sights, and a mid-length gas system provides smooth, reliable operation as well as a reduction in felt recoil.
