Description

Combat-Proven SOPMOD Block II Pedigree with State-Compliant Integration The Daniel Defense M4A1 carbine carries forward the exact tactical specifications of the weapon system deployed by US Special Operations Command (SOCOM) for the SOPMOD Block II program since 2005. Engineered to handle the rigorous demands of military operators and professional law enforcement, the M4A1 provides absolute zero retention, rugged durability, and uncompromising dependability. This variant is specifically configured for compliance in restricted jurisdictions without sacrificing core tactical capabilities.

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 rock-solid zero for lasers, illuminators, and optics 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 legal overall barrel 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 & State-Compliant Factory 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 10-round Magpul PMAG to ensure immediate, lawful deployment in restricted states.
