The Daniel Defense M4A1 is a rifle model that closely replicates the iconic M4A1 carbine used by the U.S. military. It is a reliable and high-performance firearm that offers versatility and exceptional quality. The M4A1 model is designed for a wide range of applications, including military, law enforcement, and civilian use. It is a semi-automatic, magazine-fed carbine that embodies the features and characteristics of the military M4A1. The M4A1 typically features a 14.5-inch barrel length, made from chrome-moly vanadium steel. This length strikes a balance between maneuverability and ballistics performance, making it suitable for close-quarters engagements and general-purpose use. The M4A1 is chambered in 5.56x45mm NATO/.223 REM calibers, commonly used in military and law enforcement settings. The Daniel Defense M4A1's adherence to the M4A1 carbine's military specifications is one of its most notable characteristics. This includes features such as the M4A1 marked lower receiver, the M4A1-style F-marked front sight base, a collapsible buttstock, and a removable carrying handle. The M4A1 also incorporates Daniel Defense's renowned quality and craftsmanship. It often features a free-floating, quad-rail handguard for accessory attachment, ambidextrous controls, and a chrome-lined chamber and bore for enhanced durability and reliability.
