Description

Built for personal defense, tactical training, duty use, and serious recreational shooting, the Daniel Defense DDM4 M4A1 RII AR-15 5.56 NATO combines legendary SOCOM-proven design with modern refinements and premium components that set it apart from standard AR-15s.

Ready for demanding environments and serious shooters — this is one of the most respected and capable 5.56 rifles on the market today. 

At its core is a 14.5-inch Cold Hammer Forged, chrome-lined M4-profile barrel with a 1:7 twist rate, permanently pinned with a Daniel Defense flash suppressor for a legal 16-inch overall length. This setup delivers exceptional accuracy, long barrel life, and consistent performance with virtually any 5.56 NATO ammunition. The proven carbine-length direct impingement gas system ensures smooth, reliable cycling even under sustained fire. 

The Daniel Defense DDM4 SB-22 M4A1 RII is a premium, battle-ready AR-15 built to the highest standards of reliability and performance. Featuring the iconic RIS II quad rail system — the same rail trusted by U.S. Special Operations Command (SOCOM) since 2005 — this rifle brings genuine SOPMOD Block II heritage to civilian and professional shooters who demand uncompromising quality.
