Daniel Defense DD4™ RIII™ S

The DD4 RIII S AR15 style firearm features a fully ambidextrous lower that allows both left- and right-handed shooters 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 10.5 inch RIS III rail—modeled after the revolutionary RIS II two-piece handguard developed for SOCOM—features M-LOK attachment for lighter weight and surrounds a free-floating, Cold Hammer Forged 11.5 inch Government Profile barrel. Along with the increased control provided by the ambidextrous lower, this short-barreled rifle delivers optimal maneuverability, reliability, accuracy, and terminal ballistics using a wide variety of ammunition, while its carbine length gas system provides smooth, reliable cycling under harsh conditions and reduces perceived recoil. 

This rifle also comes with the ergonomic Daniel Defense Buttstock and Pistol Grip.

FULLY AMBI FOR FULLER CONTROL

More control of your rifle means more control of the situation. Whether you're a righty or lefty, you can easily operate the bolt catch, safety selector, and mag-release button without moving or removing your dominant hand from the rifle's grip.

PATENTED BLAST-PROOF 6-BOLT ATTACHMENT

We use the same battle-tested 6-Bolt, Bolt-Up System developed for our RIS II rails, which provides robust mounting, strong enough to withstand recoil from grenade launchers.

REMOVABLE & COMPATIBLE FOR MORE ATTACHMENT OPTIONS

Versatile two-piece design allows for removal of the lower rail section and easy attachment of M203 (or M320 with adapters) grenade launcher (RIS III 12.5 and 13.0 rails only).

GET A GRIP & LET IT RIP

Ambidextrous GRIP-N-RIP charging handles provide a secure grip and even more flexibility for right- and left-handed shooters. Plus, these ingenious handles are designed with our anti-gas feature to keep gas away from your face and provide a better shooting experience.
