The Daniel Defense M4 Carbine V5 is perfectly adapted for end-users who plan on attaching the ever popular red dot, holographic or magnified optics to their firearm. The slick top monolithic upper receiver provides operators with valuable top rail real estate for accessories that fit their shooting needs. The V5 is equipped with a single pinned low-profile gas block that is drilled, taper reamed, and press fit into place to securely attach to the barrel assembly. This creates a rock solid platform that will never let you down. Like DD's other M4 Carbines, the V5 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. A Daniel Defense DDM4 Rail that makes the V5 endlessly customizable and an A2-style vertical grip provides a firm, secure hold in any shooting situation. The Magpul MOE buttstock is adjustable for length-of-pull. 30-round Magpul PMag and full-latch impact plastic case included. Made in the USA.
