Daniel Defense M4A1, Semi-automatic Rifle, 223 Remington/5.56 NATO

Product Description

The DD M4A1 556NATO 14.5″PB BLK/FDE 32RD is a licensed, military-specification M4A1 carbine built to the exact standard of current US military issue. Moreover, this rifle combines Daniel Defense’s engineering with proven ergonomics and modularity. Every firearm is hand assembled, quality assurance tested, and test fired before it ships.

The RIS III rail system defines this build. Additionally, it uses Daniel Defense’s patented 6-bolt Bolt-Up System for superior zero repeatability. The 14.5-inch cold hammer forged barrel includes a pinned-and-welded muzzle device, maintaining legal Title I compliance at 16 inches total.

M-LOK slots on the RIS III accept modern lights, lasers, and tactical grips without the bulk of legacy quad-rail designs. Therefore, this rifle balances combat-proven features with practical accessory integration. It’s built for serious shooters, law enforcement, and military enthusiasts.
