The AR-15 platform's modularity allows for endless customization, and one increasingly popular modification is the side charging upper receiver. This guide delves into the benefits, drawbacks, and considerations involved in choosing a side charging upper for your AR-15. We'll explore the mechanics, various types available, and help you determine if this upgrade is right for your needs.
What is a Side Charging Upper Receiver?
A side charging upper receiver replaces the standard AR-15 charging handle located on the rear of the receiver with a charging handle mounted on the side. This seemingly small change offers several advantages, particularly for users prioritizing specific operational characteristics. Instead of reaching over the top of the receiver, the shooter manipulates the charging handle from the side, often with their support hand.
Advantages of Side Charging Uppers
- Ambidextrous Operation: The most significant benefit is ambidextrous operation. Both right and left-handed shooters can easily charge the weapon without compromising their grip or shooting position.
- Improved CQB Capabilities: In close-quarters combat (CQB) scenarios, the side charging handle allows for faster weapon manipulation while maintaining a secure firing grip. This is particularly beneficial when operating in confined spaces or using accessories like red dot sights or night vision devices.
- Reduced Optic Interference: The side charging handle eliminates the potential for interference with mounted optics, like scopes or magnified red dots, that can occur with the traditional top-mounted charging handle.
- Enhanced Use with Suppressors: When using a suppressor, the side charging upper allows for smoother operation and reduces the risk of damaging optics or the suppressor itself during charging.
- Improved Ergonomics: For some shooters, the side charging handle offers a more ergonomic and natural charging motion, leading to improved speed and control.
Disadvantages of Side Charging Uppers
- Increased Cost: Side charging uppers are generally more expensive than standard uppers. The more complex design and manufacturing process contribute to the higher price point.
- Potential for Reliability Issues: Some users report increased reliability issues with certain side charging upper designs. This can include malfunctions related to gas port placement, bolt carrier group compatibility, and the charging handle mechanism itself. Thorough research and choosing a reputable manufacturer are crucial to mitigate this risk.
- Learning Curve: While intuitive for many, there's a slight learning curve involved in transitioning from a traditional charging handle. This is usually minimal and quickly overcome with practice.
- Weight: Side charging uppers may be slightly heavier than standard uppers depending on the design and materials used.
Choosing the Right Side Charging Upper
Consider these factors when selecting a side charging upper:
- Manufacturer Reputation: Choose a reputable manufacturer known for quality and reliability. Research reviews and compare different brands before making a purchase.
- Materials: High-quality materials are essential for durability and longevity. Look for uppers made from aircraft-grade aluminum or other robust materials.
- Compatibility: Ensure the upper receiver is compatible with your existing lower receiver, bolt carrier group, and other components. Some side charging uppers might require specific BCGs for optimal function.
- Charging Handle Design: Different side charging handles offer varying degrees of ease of use and ergonomics. Consider the size, shape, and location of the charging handle to find what best suits your needs.
Conclusion
Side charging upper receivers offer significant advantages for certain users and applications, particularly in CQB and situations where ambidextrous operation and optic clearance are crucial. However, it's essential to weigh the potential drawbacks, including cost and potential reliability concerns, before investing in this upgrade. By carefully researching and selecting a high-quality product from a reputable manufacturer, you can effectively enhance your AR-15's functionality and performance. Remember to always practice safe gun handling and follow all applicable laws and regulations.
