The Daniel Defense DD4 M4A1 RIII in 5.56x45mm/.223 Remington (MPN 02-191-04238-047) is a fully ambidextrous AR-15 pattern rifle that lets left- and right-handed shooters operate the bolt catch, safety selector, and magazine release without moving their dominant hand. Daniel Defense replaces the original M4A1’s quad rail with a lighter 12.5-inch RIS III rail featuring M-LOK attachment while retaining M203 grenade-launcher compatibility, built around a 14.5-inch cold hammer forged government-profile barrel with a 1:7-inch twist. A pinned and welded Daniel Defense flash suppressor extends the barrel to meet the 16-inch minimum length required by federal law, and the ambidextrous GRIP-N-RIP charging handle rounds out the controls. The rifle feeds from a 32-round magazine, with a 30-round magazine included, and ships with no factory sights, finished in black and FDE. Among AR-platform rifles in the AR rifles category, the DD4 M4A1 RIII favors shooters who want a lighter-weight, fully ambidextrous carbine.
