AR-15 A2 Upper Receiver: Everything You Need to Know

The AR-15 rifle is one of the most popular firearms in the United States. The versatility and customization options it offers make it a favorite among gun enthusiasts, hunters, and law enforcement agencies alike. The A2 upper receiver is one of the key components that make up an AR-15 rifle.

What Is an AR-15 A2 Upper Receiver?

The upper receiver is the part of an AR-15 that houses the bolt carrier group, charging handle, barrel assembly, gas system, and handguard. It also contains other critical components like dust cover assemblies and forward assist mechanisms. The A2 upper receiver comes with a variety of enhancements over its predecessor -the A1.

One notable feature found on all genuine Colt-made versions was its fully adjustable rear sight assembly which allowed for windage changes as well as elevation adjustments out to 800 meters in 50-meter increments (known as "meter clicks").

Comparison: A1 vs. A2 Upper Receivers

The main difference between these two receivers lies in their sights configurations:

Sights Configurations

The original M16s were equipped with triangular front sights molded directly into their fixed carrying handles while also featuring peep-hole style rear iron-sights mounted onto their removable carrying handles.

  • A1: These early models featured a relatively simple design with limited adjustments available for sighting purposes.
  • A2: With upgraded features such as fully adjustable rear iron-sights housed within built-in mounts atop receivers plus improved forward-mounted sling-swivel positions located near barrels' ends (eliminating need for separate swivels attached along forearms), these rifles offer significantly increased accuracy levels compared against earlier editions.

Handguard Design

Another major difference between both generations lies within their handguards:

  • A1: Features ribbed heat-shields formed into handguards' interiors
  • A2: Features round and smooth handguards with a heat-shield that surrounds the barrel.

Flash Suppressors

The M16A1 was fitted with a "duck-bill" shaped flash suppressor which proved to be less effective than its successor -the "bird-cage" style found on A2s.

Benefits of AR-15 A2 Upper Receiver

Here are some of the benefits you can get from using an AR-15 A2 upper receiver:

Enhanced Accuracy

Thanks to its improved sights system, an A2 upper receiver offers better accuracy compared to earlier models. The fully adjustable rear sight assembly provides more precise windage and elevation adjustments, making it easier for shooters to achieve their desired point of impact.

Reliability

With forward-mounted sling-swivel positions located near barrels' ends (eliminating need for separate swivels attached along forearms), these rifles offer significantly increased reliability levels compared against earlier editions.

Customization Options

The smooth round handguard design makes it easier for users to add rails or attachments without having sharp edges that may potentially cause discomfort while handling or firing your rifle. This feature allows gun owners infinite customization possibilities when it comes down outfitting their firearms exactly how they want them tailored specifically towards their intended purposes whether hunting, competition shooting sports or self-defense needs.

Tips On Maintaining Your AR-15 Upper Receiver

As with any firearm component, proper maintenance is crucial in ensuring optimal performance. Here are some tips on maintaining your AR-15 upper receiver:

  • Always keep your rifle clean and lubricated.
  • Check all screws regularly; ensure they’re tight.
  • Don't use corrosive ammo as this may damage parts beyond repair over time if left unchecked.
  • Use high-quality cleaning kits when performing routine maintenance tasks such as bore cleaning as these accessories will help prolonging components' longevity by minimizing wear/tear from unnecessary frictional forces during cleaning cycles.

Conclusion

The AR-15 A2 upper receiver is a significant upgrade that provides enhanced accuracy, reliability, and customization options compared to its predecessors. It's a highly versatile component designed to meet the needs of gun enthusiasts, hunters, law enforcement agencies around the world. By following proper maintenance guidelines and taking advantage of all available features this product offers -you'll be sure enjoying years' worths shooting experiences without having to worry about any parts failing or wearing out prematurely.

An AR-15 A2 upper receiver is an essential component of the AR-15 rifle. It houses the components that allow the rifle to fire and operate, such as the barrel, bolt carrier group, charging handle, gas tube assembly, and forward assist.

How does an AR-15 A2 Upper Receiver differ from other Upper Receivers?

There are several key differences between an ar 15 a1 vs a2 vs b5 uppers , but for this FAQ section we will be comparing it primarily with later models like ar 10 uppers instead.

Another major characteristic differentiating it's compatibility with ammunition specifically designed for making longer range shots compared some more current models like LMT MARS-L (Modular Ambidextrous Rifle System), KAC SR25 (Stoner Rifle) etc.

Is it possible to upgrade my existing lower receiver with An Ar – 10 than switching out my entire gun?

No! Lower receivers cannot be easily swapped out between these two firearms due because they are designed differently and have different dimensions. The AR-10 has a larger frame and magazine well, for example, which means that an AR-15 lower receiver would not fit properly.

That being said, there are some manufacturers who have produced "hybrid" receivers that can accommodate both AR-15 and AR-10 components. However, these are not very common and may not be compatible with all parts or accessories.

Can I use an A2 Upper Receiver on my other rifles?

If your rifle uses the same specifications as the M16A2/M4A1 platform such as barrel length ,forward assist assembly configuration e.t.c then it is possible to use this type of upper receiver on it but you should always verify compatibility before making any modifications to your firearm.
