When looking for a top quality AR15, Daniel Defense is one of the names that immediately comes to mind. The M4A1 is a carbine that only needs your sights or optics to be truly a "combat ready" weapon.From its 14.5" cold hammer forged barrel with permanently attached flash suppressor to the Mil Spec+ Cerakote finish, every inch of this rifle speaks of quality and attention to detail. It features the Daniel Defense M4A1 Rail Interface System (RIS) II handguard and rail system, which has been in use by US Special Operations Command (SOCOM) since 2005, and comfortable soft-touch overmolding on the butt stock and pistol grip.
