KeyMod system integrated in the 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. SLiM RAIL 15.0 offers weight savings as well as cooling, ergonomics and modularity while maintaining strength and durability. The 15 inch rail gives operators the option to have the support hand extended out close to the muzzle allowing them to drive the gun more precisely and prevents over travel when transitioning between multiple targets. 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. Equipped with a free-floating, cold hammer forged, chrome lined barrel, newly designed Daniel Defense buttstock and pistol grip with DD improved flash suppressor.
