"The Daniel Defense M4A1 Semi-Auto Rifle is a precision-built, fully ambidextrous AR-15 utilizing the finest components made in-house by Daniel's expert staff. With the success of earning government contracts with USSOCOM, the M4A1 is a proven platform you can rely on to perform in the worst conditions. The ambidextrous lower receiver allows both right- and left-handed shooters to operate the bolt catch, safety selector, and magazine release without having to remove their dominant hand from the rifle's grip. The rifle is built around a 14.5"" cold hammer-forged, government-profile barrel with a permanently attached flash suppressor, bringing the barrel to legal length. The stock is Daniel Defense's own creation, featuring soft rubber overmolding and 6-position adjustability. The Daniel Defense pistol grip features the ideal wrist angle and is also overmolded for comfort. If you want the finest example of the classic direct-impingement carbine, look no further.
