The Daniel Defense M4A1 is a semi-automatic rifle built around the combat-proven M4A1 RIS II rail system. Its 14.5-inch cold hammer forged M4-profile barrel uses a 1:7 twist and is fitted with a Daniel Defense flash suppressor that is permanently pinned and welded to produce a legal 16-inch barrel length. The rifle features forged 7075-T6 aluminum receivers, M4 feed ramps, a pinned low-profile gas block, and an M16-profile chrome-lined bolt carrier with a magnetic particle tested bolt. The RIS II handguard provides a rigid, full-length platform for mounting lights, lasers, foregrips, and other accessories. Daniel Defense furniture includes a six-position adjustable stock and an overmolded pistol grip designed for secure handling.
