<p>The Daniel Defense M4A1 AR-15 Rifle is an immediately-recognizable AR-15 platform with a large amount of community respect due to its construction of hard-use, true mil-spec parts. With the success of earning government contracts with US SOCOM, the Daniel Defense M4A1 AR-15 Rifle is a favorite for many shooters. The direct impingement gas system features a low-profile gas block and carbine-length gas tube. The DD RIS (Rail Interface System) II Picatinny quad rail handguard is CNC machined from 6061-T6 aluminum and finished in type 3 hard coat anodizing. The receiver group is machined from 7075-T6 aluminum. The M16 bolt carrier group is MP tested, chrome lined, and featured a properly staked gas key. Engineered for suppressed fire, the DD GRIP-N-RIP charging handle redirects gases away from the user's face. The charging handle is also ambidextrous for left and right-handed use. The Daniel Defense rubber overmolded grip is a nice touch and pairs well with their rubber rail-panel covers and overmolded stock, both of which are included. DD is a well-trusted brand with combat-grade, quality components. The extra confidence that comes with the name makes it a nice addition as combat effective platform to your collection.</p> <ul> <li class=>DD's take on the M4A1 AR-15 Rifle</li> <li class=>Carbine-length DI gas system<br></li> <li class=>DD Flash suppressor</li> <li class=>DD RIS II Picatinny quad rail</li> <li class=>DD collapsible stock</li> <li class=>M16 BCG</li> <li class=>DD GRIP-N-RIP ambidextrous charging handle</li> <li class=>Rubber overmolded pistol grip</li> <li class=>Rubber rail panel covers</li> </ul>
