Daniel Defense M4A1 RIII Black 5.56 / .223 Rem 14.5 P&W Barrel 32-Rounds

Overview

Daniel Defense M4A1 RIII Features Daniel Defense M4A1 RIII is built around a 14.5-inch government profile barrel pinned and welded to a muzzle device for a compliant 16-inch overall barrel length chambered in 5.56 NATO with .223 Remington compatibility and a 1:7-inch twist rate optimized for stabilizing a wide range of projectile weights. The mid-length gas system provides a longer dwell time and softer recoil impulse compared to carbine-length gas systems improving reliability and reducing wear on the bolt carrier group over sustained use. A nickel boron bolt carrier group offers enhanced corrosion resistance reduced friction and easier cleaning compared to standard phosphate-coated components. The M4A1 RIII platform follows the proven M4A1 military configuration delivering the ergonomics handling and reliability that have made the M4A1 the standard for modern fighting rifles across decades of service. The B5 Systems CAR-15 stock provides a durable mil-spec buffer tube compatible replacement with positive lock-up at each length-of-pull position for a consistent cheek weld. A polymer grip completes the fire control interface on a lower receiver built to Daniel Defense s tight manufacturing tolerances. Daniel Defense s RIII designation reflects a commitment to verified reliability with each rifle subjected to rigorous quality control standards before leaving the factory. The nickel boron bolt carrier group and mid-length gas system work in concert to produce a smooth consistent cycling action that performs across a wide range of ammunition and environmental conditions. One 32-round Daniel Defense magazine is included providing immediate high-capacity use from the factory.
