The original Daniel Defense Rifle, The Daniel Defense M4 Carbine created the definition of tactical perfection. Built to redefine the benchmark in small arms performance, this precision-crafted firearm will perform faithfully in any military, law enforcement, homeland security, and personal security environment. The M4 Carbine has a mil-spec lower receiver with an enhanced, flared magazine well and a rear receiver QD swivel attachment point. The upper receiver is mil-spec as well with indexing marks and M4 feed ramps. The M4's barrel is made of cold-hammer forged moly vanadium steel with a mil-spec heavy phosphate external coating and internal chrome-lining. Every V2 M4 Carbine comes with a Daniel Defense DDM4 Rail that makes it endlessly customizable. The Magpul MOE buttstock is adjustable for length-of-pull. This rifle features a post front sight, an adjustable aperture rear sight, a 2-position thumb safety, and a 30-round magazine. Its stock, metal, and bore are all in very good condition.
