The M4A1 RIII updates Daniel Defense’s classic M4A1 with a lighter 12.5″ RIS III M-LOK handguard and a fully ambidextrous lower. A pinned and welded flash suppressor brings the 14.5″ chrome-lined barrel to a legal 16″ length, and the mid-length gas system softens the recoil impulse. Sights are sold separately.
