Daniel Defense DDM4A1 RII 5.56 NATO 14.5" Pinned and Welded Black 32+1 SB-022

Daniel Defense DDM4A1 RII

The Daniel Defense DDM4A1 RII is a premium duty-grade AR-15 carbine chambered in 5.56 NATO, built around the battle-proven M4A1 RIS II quad-rail handguard adopted by U.S. Special Operations Command for the SOPMOD II program. Featuring a 14.5-inch cold hammer-forged M4-profile barrel with a permanently attached Daniel Defense flash suppressor to achieve a legal 16-inch overall length, this rifle delivers exceptional durability, accuracy, and modularity in a compact, hard-use package. Ambidextrous controls, quick-detach sling points, and a full-length Picatinny rail ensure maximum adaptability for optics, lights, lasers, and grips.

The free-float quad-rail design provides extensive accessory mounting options while maintaining rigidity and heat dissipation, complemented by a carbine-length gas system for smooth, reliable cycling across various loads. Daniel Defense furniture, including the ergonomic buttstock and pistol grip, enhances shooter comfort and control during extended use or dynamic engagements. Ships with one 32-round Daniel Defense magazine and a full-latch impact plastic case for immediate field readiness and secure transport.

Designed for law enforcement, military professionals, serious enthusiasts, or anyone requiring a top-tier 5.56 carbine, the DDM4A1 RII combines legendary Daniel Defense craftsmanship with proven SOCOM-spec components to deliver unmatched reliability, precision, and customization in demanding real-world applications.
