Colt AR-15 A2: An Iconic Rifle for Military and Civilian Use

The Colt AR-15 A2 is an iconic rifle that has been used by military personnel, law enforcement agencies, and civilians worldwide since the 1960s. This rifle has undergone several modifications over the years to make it more versatile, reliable, and accurate.

History of Colt AR-15 A2

Colt Defense LLC designed the first ArmaLite AR-15 in 1959 as a lightweight assault rifle for military use. The U.S Army adopted this weapon in 1963 as M16A1 which later replaced M14 rifles. It was during this period that Colt began manufacturing semi-automatic versions of its military rifles for civilian use under the name "AR-15". One such version was the Colt AR-15A2.

The original design of ArmaLite featured a plastic stock, a fiberglass handguard with triangular cross-sections enclosing an aluminum barrel sleeve with cooling fins underneath it; sights consisting only of adjustable rear aperture sight mounted on top cover were improved upon by adding windage-adjustable front sight post at muzzle end making room available to add detachable carrying handle or optic mounts.

In contrast to earlier models like M16A1/M16A4 series which had full automatic firing mode enabled too besides semi-automatic mode (single shot), all civilian models have always been limited to single fire only so they can be legally purchased without requiring any special license except where state laws dictate otherwise.

Design Features

The current model features several design changes from earlier versions including:

  • Integrated carry handle
  • Windage-adjustable front sight
  • Adjustable elevation rear peep or aperture sights
  • Fixed buttstock made from thermoplastic materials
  • Standardized trigger components
  • Improved receiver forging process.

One significant feature is its weight – just about six pounds unloaded – making it easy-to-handle. The lightweight design also makes it easy to carry for extended periods of time, making it a popular choice among civilian hunters and competition shooters.

Advantages of Colt AR-15 A2

The Colt AR-15 A2 is one of the most reliable rifles available today because it has been built with top-quality materials and expertise. It offers many benefits such as:

  1. High accuracy: The rifle comes equipped with adjustable sights that allow for precise shooting at long ranges.
  2. Customizable: Its modular design allows users to change critical components like handguards, stocks, triggers, etc., quickly.
  3. Low recoil: Due to its gas-operated system instead of traditional piston operated systems which reduce felt recoil providing more control over the gun.
  4. Versatile calibers: Some versions can fire different calibers making them useful in various scenarios.

Comparing Colt AR-15 A2 With Other Rifles

Colt AR-15 A2 compares favorably against other rifles like AK series or M14 in terms of ergonomics and weight but may not be suitable in certain situations because there are better options available depending on your needs.

AK Series are known for their durability but weigh almost double compared to an unloaded ArmaLite (7+ pounds) hence increasing fatigue when carrying around all day while M14's additional firepower (semi-automatic/full automatic modes) is offset by being heavier than both ArmaLites & AKs weighing 9+ pounds that makes mobility cumbersome except when firing from a fixed position/cover.

Tips for Using Colt AR-15A 2

Here are some tips on how to use this iconic rifle effectively:

  1. Always check if the weapon is clean before using

    • Check barrel condition
    • Inspect trigger assembly

    Regular cleaning will keep your gun functional during emergency situations without any malfunction caused due to debris accumulation inside mechanisms.

  2. Use high-quality ammunition

    • Choose from reputable brands
    • Avoid anything that looks abnormal like loose tips or discoloration

    High quality of ammunition will ensure that your rifle fires accurately and continuously without any misfires, jams or malfunctions.

  3. Train regularly with your weapon

    • Practice shooting at different ranges
    • Take tactical training classes for added proficiency

    Regular practice helps you become familiar with the rifle's features, understand its limitations so you can make quick decisions in life-threatening situations.


The Colt AR-15 A2 is a versatile and reliable rifle designed to meet military standards while also catering to the civilian market. The modular design allows users to customize the weapon according to their needs, making it an ideal choice for hunting, competition shooting or self-defense.

Its lightweight design makes it easy-to-handle and carry for extended periods of time without causing fatigue. With regular maintenance and proper handling techniques along with good quality ammunition combined with regular training sessions; this iconic gun will provide years of dependable service whether in professional use by law enforcement/military personnel or recreational shooters who share an interest in firearms collection/sporting activities

Another noteworthy feature of this weapon system includes its use of full-length handguards protecting more barrel length than its counterparts.
