RIS II Quad Rail & Pinned Barrel Architecture
-
M4A1 RIS II Quad Rail: The free-floating 12.25-inch Picatinny quad rail utilizes a patented bolt-up system that allows the barrel to float freely, preserving barrel harmonics and maintaining zero for lasers, illuminators, and optics even under heavy firing schedules.
-
14.5″ Cold Hammer Forged Barrel: Constructed from Chrome Moly Vanadium steel with a 1:7 twist, chrome lining, and heavy phosphate coating. Individually HP/MPI tested, it is paired with a permanently pinned-and-welded Daniel Defense extended flash suppressor to satisfy non-SBR overall length requirements while maintaining optimal duty maneuverability.
-
Carbine-Length Gas System: Equipped with a pinned low-profile gas block and an H buffer to ensure smooth, reliable cycling across diverse ammunition types.
Enhanced Controls & Complete Armory Configuration Outfitted with the independently ambidextrous GRIP-N-RIP charging handle, heat-resistant Santoprene rail panels (rated to 300° F), Daniel Defense’s ergonomic overmolded buttstock and pistol grip, and a factory Daniel Defense 32-round magazine.
