The Daniel Defense M4 Carbine V11, based on the popular V9 series, was designed for shooters who prefer the benefits of the KeyMod system integrated in the new SLiM Rail™ (Slim Lightweight Modular). KeyMod is a recoil resistant, two-part, direct attachment method for accessories that offers outstanding “return-to-zero” when accessories are removed and reinstalled. The new SLiM Rail™ 15.0 offers incredible weight savings as well as superior cooling, ergonomics and modularity while maintaining the strength and durability expected from Daniel Defense. The long, 15” rail gives operators the option to have the support hand extended out closer to the muzzle allowing them to drive the gun more precisely and prevents over travel when transitioning between multiple targets. This combined with our mid-length gas system, which is known to have a smoother recoil impulse, allows for quick, but precise rapid fire. An uninterrupted picatinny rail on top and KeyMod attachment at 3, 6, and 9 o’clock, ensures plenty of real estate for optics and accessories and allows for maximum sight radius for accurate shooting with rail mounted iron sights. The DDM4V11 is equipped with a free-floating, Cold Hammer Forged, 16” Government profile barrel and the newly designed, rugged and comfortable Daniel Defense Buttstock and Pistol grip.
