The DD4 RIII features a fully ambidextrous lower receiver with mirrored magazine release, bolt catch, and safety selector, allowing intuitive control from either shoulder.
Its 16-inch chrome-moly-vanadium steel barrel is cold-hammer-forged in-house, chrome-lined for extended service life, and threaded 1/2-28 TPI for standard muzzle devices or suppressor mounts.
The 12.5-inch RIS III free-float handguard retains the SOCOM six-bolt interface, adds M-LOK slots for modern accessories, and remains compatible with 40 mm grenade launchers for professional users.
A lightweight 7075-T6 aluminum receiver set with black hard-coat anodizing keeps weight to just 6.52 lb unloaded, while the collapsible Daniel Defense stock, soft-touch over-mold pistol grip, and integrated QD sling sockets optimize ergonomics.
