The AR9 platform, chambered in 9mm, offers a compelling blend of familiarity and versatility for pistol-caliber carbine enthusiasts. One intriguing feature gaining popularity is the side charging upper receiver. But what exactly makes these uppers different, and are they the right choice for you? This guide delves into the advantages, disadvantages, and considerations surrounding side charging AR9 uppers.
Understanding the Appeal of Side Charging
Traditional AR-style uppers utilize a charging handle located at the rear of the receiver. While functional, this design presents some drawbacks, especially in close-quarters situations or when operating with accessories like optics or suppressors. This is where the side charging upper shines.
Key Advantages of Side Charging AR9 Uppers:
- Improved Ergonomics: The side charging handle allows for ambidextrous operation and smoother manipulation, particularly when using a red dot sight or other accessories mounted on the top rail. This is especially beneficial for left-handed shooters.
- Enhanced Accessibility: The side charging handle can be easier to reach and manipulate in confined spaces or when using specialized equipment. This can be crucial in tactical situations or when working in tight quarters.
- Reduced Bolt Carrier Interference: The side charging handle eliminates the potential for interference with optics or other accessories mounted on the top rail. This is a significant advantage for those who prefer a more streamlined setup.
- Faster Follow-Up Shots: For some shooters, the side charging handle allows for faster manipulation and quicker follow-up shots. This is a subjective advantage, depending on individual shooting techniques and preferences.
Potential Drawbacks to Consider
While side charging uppers offer numerous benefits, it's crucial to acknowledge potential downsides:
Disadvantages of Side Charging AR9 Uppers:
- Increased Cost: Side charging uppers are often more expensive than their traditional counterparts due to the more complex manufacturing process.
- Potential for Reliability Issues (in some designs): While many reputable manufacturers produce reliable side charging uppers, some less established brands might have issues with reliability. Always research the manufacturer thoroughly before purchasing.
- Ambidextrous Charging Handle Considerations: While ambidextrous operation is a key benefit, some shooters find that the added weight and bulk of ambidextrous charging handles can slightly impact handling.
- Increased Complexity: The mechanism of a side-charging system is inherently more complex than a standard rear charging handle, potentially increasing the likelihood of malfunction if not properly maintained.
Choosing the Right AR9 Upper for Your Needs
The decision of whether or not to choose a side charging AR9 upper hinges on your individual needs and preferences. Consider these points:
- Shooting Style: Do you frequently shoot in close quarters or utilize specialized accessories? If so, a side charging upper might offer distinct advantages.
- Budget: Side charging uppers are typically more expensive. Factor this into your budget considerations.
- Reliability and Manufacturer Reputation: Choose a reputable manufacturer with a proven track record of producing reliable firearms. Read reviews and do your research.
- Maintenance: Be prepared to maintain your firearm properly. The more complex mechanism of a side-charging system requires consistent and diligent maintenance.
Conclusion
Side charging AR9 uppers present a viable and potentially superior option for certain applications and shooters. However, they are not without their drawbacks. Careful consideration of your individual needs and preferences, along with thorough research into manufacturers and reviews, is crucial before making a purchasing decision. Weighing the advantages and disadvantages outlined above will help you determine if a side-charging AR9 upper is the right choice for your shooting needs.
