The AR-15 platform's enduring popularity stems from its modularity and adaptability. One of the most recognizable features, especially among enthusiasts familiar with its military lineage, is the A2 carry handle upper receiver. This isn't just a nostalgic piece of firearm history; it's a functional component with distinct advantages and disadvantages that warrant a closer look. This article will delve into the details of the A2 carry handle upper, exploring its design, functionality, pros, cons, and its place in the modern AR-15 world.
Understanding the A2 Carry Handle Upper Receiver
The A2 carry handle upper receiver distinguishes itself from its modern counterparts primarily by its integrated carry handle, which houses the rear sight. This design, born from the M16A2 rifle, offers a unique blend of functionality and aesthetics. The integral carry handle provides a sturdy, reliable sighting system that's built directly into the upper receiver, eliminating the need for separate rear sight mounting. This results in a sleeker profile and reduced weight compared to systems using a separate carry handle or optic. However, this integration also presents limitations, which we'll explore later.
Key Features of the A2 Upper:
- Integrated Carry Handle/Rear Sight: This is the defining feature, offering a robust, built-in sighting solution.
- Forward Assist: Typically included, aiding in chambering rounds.
- Ejection Port Cover: Protects the ejection port from debris.
- Dust Cover: Shields the bolt carrier group from dust and dirt.
- Picatinny Rail (Often Limited): While some variations offer more extensive Picatinny rails, most A2 uppers feature only limited space for accessories.
Advantages of the A2 Carry Handle Upper
Despite its age, the A2 carry handle upper retains certain advantages appreciated by many shooters:
- Simplicity and Reliability: The design is inherently simple and rugged, making it less prone to malfunctions. Fewer moving parts translate to greater reliability.
- Cost-Effective: Generally, A2 uppers are more affordable than modern uppers with full-length Picatinny rails.
- Classic Aesthetic: Many shooters appreciate the nostalgic appeal and classic military look of the A2 design.
- Built-in Sighting System: The integrated carry handle provides a dependable sighting system without the need for additional components.
Disadvantages of the A2 Carry Handle Upper
While the A2 upper offers several advantages, it also has limitations that have contributed to its decline in popularity among some shooters:
- Limited Rail Space: The lack of a full-length Picatinny rail severely restricts the mounting of accessories such as optics, lasers, and lights.
- Lower Sight Radius: The lower sight radius compared to modern optic setups can impact accuracy at longer ranges.
- Bulkier Design: The integrated carry handle makes it bulkier than a flattop upper receiver, potentially hindering maneuverability in close quarters.
- Incompatibility with Modern Optics: Direct mounting of modern scopes or red dot sights onto the carry handle is generally impossible, necessitating alternative solutions like separate mounts.
The A2 Upper in the Modern Shooting World
The A2 carry handle upper isn't obsolete. It remains a viable option for shooters who prioritize simplicity, reliability, and affordability. It's particularly suitable for applications where the need for extensive accessories is minimal, such as basic marksmanship training or certain types of hunting. However, for those who require the versatility and customization offered by modern optics and accessories, a flattop upper receiver is generally the preferred choice.
Conclusion: Choosing the Right Upper Receiver
The choice between an A2 carry handle upper and a flattop upper depends entirely on the shooter's individual needs and preferences. Understanding the advantages and disadvantages of each design is crucial for making an informed decision. If you value simplicity, reliability, and cost-effectiveness, and don't require a plethora of accessories, the A2 upper might be a great option for you. However, if you prioritize modularity, versatility, and the ability to utilize modern optics, a flattop upper receiver would likely be the better choice.
