The A2 carry handle upper receiver is a classic piece of AR-15 history, recognizable for its integrated carry handle and distinctive profile. For many, it represents a nostalgic connection to the platform's origins, while for others, it's a practical choice offering a specific set of advantages. This guide delves into the specifics of the A2 upper, exploring its features, benefits, drawbacks, and considerations for potential buyers.
Understanding the A2 Carry Handle Upper Receiver
The A2 upper receiver is characterized by its top-mounted carry handle, which incorporates the rear sight. This integrated design, while traditional, offers a distinct set of pros and cons compared to modern flattop uppers. It's crucial to understand these differences before making a purchasing decision.
Key Features:
- Integrated Carry Handle and Rear Sight: This is the defining feature. The rear sight is built into the carry handle, eliminating the need for a separate rear sight. This simplifies the setup and reduces the overall weight (slightly).
- Forward Assist: Most A2 uppers retain the forward assist, a lever that aids in chambering a round. While debated by some, it provides a tactile reassurance for many shooters.
- Dust Cover: The dust cover protects the ejection port from debris and is a standard feature on most AR-15 uppers.
Advantages of an A2 Upper Receiver
- Simplicity and Reliability: The design is straightforward and proven reliable over decades of use. Fewer parts generally mean less potential for malfunction.
- Co-Witnessing: The carry handle's height allows for easy co-witnessing with many low-profile iron sights or red dot optics mounted on a lower rail.
- Sturdiness: The integrated design creates a solid, rigid platform.
- Nostalgia and Aesthethics: For many shooters, the A2 aesthetic is appealing, invoking a sense of classic military design.
Disadvantages of an A2 Upper Receiver
- Limited Rail Space: The lack of a Picatinny rail on top limits mounting options for optics beyond those that can be mounted on the carry handle itself. This can be a major drawback for those who need versatility in optic choices.
- Carry Handle Weight: While not substantial, the carry handle does add a bit of extra weight compared to a flattop upper.
- Height Over Bore: The height of the carry handle can make acquiring targets with certain optics more challenging.
- Potential for Obstruction: The carry handle can sometimes interfere with the use of certain scopes or accessories.
A2 Upper Receiver vs. Flattop Upper Receiver: A Comparison
The primary difference lies in the integrated carry handle. Flattop uppers offer significantly more flexibility in optic mounting due to their full-length Picatinny rail. However, A2 uppers provide a more compact, arguably more rugged design with a built-in rear sight. The best choice depends on individual needs and preferences.
| Feature | A2 Carry Handle Upper | Flattop Upper |
|---|---|---|
| Rail Space | Limited | Full-length Picatinny Rail |
| Rear Sight | Integrated | Separate |
| Weight | Slightly heavier | Slightly lighter |
| Optic Versatility | Limited | High |
| Aesthetics | Classic, Mil-Spec | Modern |
Choosing the Right A2 Carry Handle Upper Receiver
When selecting an A2 upper, consider factors like material (aluminum is standard), manufacturer reputation, and intended use. Research different brands and read reviews to ensure you're getting a quality product. Remember to also consider compatible lower receivers and other components.
Conclusion
The A2 carry handle upper receiver holds a unique place in the AR-15 world. Its simplicity, reliability, and classic aesthetics still appeal to many. However, the limited rail space and potential compatibility issues must be carefully weighed against its advantages. By understanding its strengths and weaknesses, you can make an informed decision about whether an A2 upper is the right choice for your specific needs and shooting style.
