The Daniel Defense M4A1 features the M4A1 RIS II, which has been in use by US Special Operations Command (SOCOM) for the SOPMOD II Weapons System since 2005. The M4A1 features a 14.5” Cold Hammer Forged M4 Profile barrel with a permanently attached Daniel Defense Flash Suppressor. The new independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters and is engineered for suppressed fire, with anti-gas features that redirect gas flow upward and away from the face and operator. The M4A1 is available in black as well as our Mil Spec + Cerakote. This rifle also comes with the rugged and comfortable Daniel Defense Buttstock and Pistol Grip.
