Daniel Defense · Rifle · In Production · 2024
Overview
The M4A1 RIII updates the iconic Daniel Defense M4A1 with a fully ambidextrous lower receiver and RIS III 12.5-inch M-LOK handguard. The 14.5-inch M4-profile barrel with a pinned and welded extended flash suppressor reaches the 16-inch NFA minimum without requiring a tax stamp. The mid-length gas system provides smoother recoil than the original carbine-length setup.
