The Daniel Defense M4A1 RIII URG 14.5" Black Upper Receiver Group is a combat-ready upgrade engineered for professional shooters, defense-minded citizens, and serious enthusiasts. Built around a 14.5-inch Cold Hammer Forged M4 Profile barrel, this upper delivers battle-proven durability, longevity, and accuracy. The barrel comes fitted with a pinned and welded Daniel Defense extended flash suppressor, ensuring the legal 16-inch overall length while offering exceptional flash reduction.
The mid-length gas system enhances reliability and reduces felt recoil, creating a smoother shooting experience during rapid engagements. Its 12.5-inch RIS III rail, inspired by the SOCOM-approved RIS II, brings lighter weight and unmatched versatility with full M-LOK attachment compatibility for accessories. The included GRIP-N-RIP charging handle provides ambidextrous control, while the M16 profile bolt carrier group guarantees dependable performance in the harshest conditions.
Constructed from premium materials including 7075-T6 aluminum receivers, 4140 hardened steel gas block, and 17-4 PH stainless muzzle device, the M4A1 RIII URG is designed to meet and exceed the needs of today’s demanding shooters. Made in the USA, this is a top-tier Daniel Defense system built for mission success.
