Design and Features
The Colt AR-15A2 is a semi-automatic, magazine-fed rifle that is chambered in .223 Remington/5.56x45mm NATO.

This design allows for a lighter and more compact rifle.
One of the key features of the AR-15A2 is its modular design. It allows for various accessories and attachments to be easily mounted, such as optics, lights, and vertical grips. The rifle also features a fixed stock, which provides stability and absorbs recoil.
Military Adoption
The Colt AR-15A2 has a long history of military adoption. The original Ar-15 entered service with the United States military in the 1960s and has since become the standard-issue rifle for many branches, including the United States Army and Marine Corps. Its lightweight and reliable design make it well-suited for various combat situations.
The AR-15A2 has seen significant use in conflicts around the world. Its accuracy and versatility have made it a preferred choice for military personnel, and its reputation for reliability under harsh conditions has earned it the nickname “The Black Rifle.”
Civilian Versions
In addition to its military use, the Colt AR-15A2 has also become popular among civilians, particularly in the United States. Due to legal restrictions, civilian versions of the AR-15A2 are semi-automatic only and cannot possess certain features, such as a flash suppressor or a bayonet lug. Despite these limitations, the civilian versions retain many of the key features and overall design of the military variant.
Development and History
Origins of the AR-15
The development of the Colt AR-15A2 can be traced back to the AR-15, which was originally designed by Eugene Stoner in the 1950s. The AR-15 was initially developed for military use, but Colt later marketed it to civilian and law enforcement markets as well. The design and lightweight nature of the AR-15 made it stand out from other rifles of its time.
Colt’s Involvement
Colt acquired the rights to the AR-15 in 1959 and developed it further, leading to the creation of the AR-15A2. The company made several changes and improvements to the original design, including a more durable and reliable bolt and a heavier barrel to improve accuracy and reduce barrel wear. These changes resulted in a highly dependable rifle that became the foundation for future iterations of the AR-15 family.
Development of the AR-15A2
The AR-15A2 was introduced in the early 1980s and quickly gained popularity. It featured a number of improvements over its predecessor, the AR-15A1, including a more ergonomic pistol grip, a heavier barrel with a faster twist rate for better stability with heavier bullets, and an adjustable rear sight for improved accuracy at various distances.
The AR-15A2’s improved design and performance made it a favorite among military personnel and civilians alike. Its reputation for reliability and accuracy led to its adoption by various military forces around the world.

Key Features and Specifications
Barrel Length and Twist Rate
The Colt AR-15A2 has a 20-inch barrel, which provides a good balance between maneuverability and accuracy. The barrel also features a 1:7 twist rate, which is optimized for stabilizing heavier bullets typically used by the military. This twist rate ensures that the bullets remain stable in flight, resulting in improved accuracy and long-range performance.
Furniture and Accessories
The AR-15A2 features a fixed stock, which provides stability and control during firing. Additionally, the rifle is equipped with a handguard that allows for the attachment of various accessories, such as a bipod or a vertical grip. The rifle also has a standard MIL-STD-1913 rail on top of the receiver, which allows for the mounting of optics or iron sights.
Sights and Optics
The AR-15A2 is equipped with adjustable iron sights, consisting of a front post and a rear aperture sight. The rear sight has both windage and elevation adjustments, allowing for precise aiming at different distances. While the iron sights are effective, many users choose to mount various optics, such as red dot sights or magnified scopes, for enhanced target acquisition and accuracy.
Maintenance and Cleaning
Proper maintenance and cleaning are crucial for the longevity and reliable performance of the Colt AR-15A2. Regular maintenance ensures that the rifle functions properly and avoids malfunctions due to dirt or debris buildup.
