Daniel Defense

The ambidextrous DD4 RIII AR15 style rifle is designed to satisfy the needs of both right- and left-handed shooters in popular shooting sports and for tactical and defensive applications. Its fully ambidextrous lower allows a shooter to operate the bolt catch safety selector and magazine release without having to move or remove their dominant hand from the rifle's grip while its GRIP-N-RIP Charging Handle is fully ambidextrous as well. A 12.5 inch lightweight RIS III rail modeled after the revolutionary RIS II two-piece handguard developed for SOCOM features M-LOK attachment for lighter weight while still offering M203 grenade-launcher attachment. It surrounds a 16 inch Cold Hammer Forged Government Profile barrel and our mid-length gas system known to have a smoother recoil impulse adds to this rifle's accuracy by allowing for quick but precise rapid fire. This rifle also comes with the ergonomic Daniel Defense Buttstock and Pistol Grip. - MATERIALS & CONSTRUCTION - LOWER RECEIVER: Fully ambidextrous Mil-Spec with Enhanced Flared Magazine Well and Rear Receiver QD Swivel Attachment Point.
