Introduction:
Charging your AR-15 upper receiver from the side offers several advantages, especially in tactical situations or when using certain accessories. This method, often involving proprietary charging handles or modifications, bypasses the traditional charging handle located at the rear of the receiver. This article will explore the various methods of AR upper side charging, their pros and cons, and considerations for choosing the right system for your needs. We'll delve into the mechanics, popular brands, and potential downsides to help you make an informed decision. Understanding AR upper side charging is crucial for anyone seeking enhanced functionality and adaptability in their firearm.
Understanding AR-15 Charging Systems
The standard AR-15 charging handle is located at the rear of the upper receiver. This system is simple, reliable, and widely understood. However, side charging offers some distinct benefits, especially in specific scenarios. Let's break down the core differences:
Traditional Rear Charging Handle
- Mechanism: Pulls the bolt carrier group rearward to chamber a new round.
- Pros: Simple, familiar, readily available parts.
- Cons: Can be difficult to manipulate while using optics or other accessories; prone to malfunction if the shooter's support hand is obstructed.
Side Charging Handle
- Mechanism: Utilizes a charging handle located on the side of the upper receiver.
- Pros: Easier manipulation when using optics or accessories; improved ergonomics in certain shooting positions.
- Cons: Often requires modification or specialized uppers; potentially increased cost and complexity.
Types of AR Upper Side Charging Systems
Several approaches exist for implementing side charging on an AR-15. These include:
1. Aftermarket Side Charging Uppers
Many manufacturers offer complete upper receivers designed for side charging. These often integrate the charging handle directly into the receiver, offering a streamlined and often robust system. Examples include Radian Weapons Raptor-LT, CMMG RML, and others. These are typically more expensive but offer a clean, integrated design.
2. Conversion Kits
These kits add a side charging handle to a standard upper receiver. Installation often involves some gunsmithing skills and can void warranties. Choosing a reputable brand and following installation instructions precisely is crucial for reliability.
3. Custom Builds
Experienced gunsmiths can customize uppers for side charging, providing highly tailored solutions. This offers significant flexibility but also carries higher costs and potential risks if not done correctly.
Advantages of AR Upper Side Charging
- Improved Ergonomics: Side charging can be much more comfortable and intuitive in certain shooting positions, such as prone or behind cover.
- Compatibility with Accessories: Side charging handles often allow for unobstructed use of optics, forward grips, and other accessories that might interfere with a rear charging handle.
- Ambidextrous Operation: Many side charging systems allow for operation from either side of the rifle, beneficial for both right- and left-handed shooters.
- Tactical Advantages: In close-quarters combat or other situations requiring quick manipulation, a side charging handle can provide a significant speed advantage.
Disadvantages of AR Upper Side Charging
- Cost: Side charging systems are generally more expensive than standard rear charging handles.
- Reliability: Poorly designed or installed side charging systems can be prone to malfunctions.
- Complexity: Installation of conversion kits can be challenging and may require gunsmithing expertise.
- Weight: Some side charging systems add weight to the upper receiver.
Choosing the Right AR Upper Side Charging System
Selecting the best system depends on individual needs and preferences. Consider these factors:
- Budget: Determine how much you're willing to spend on a side charging system.
- Experience: Evaluate your mechanical aptitude for installation. If you lack experience, consider purchasing a complete upper receiver from a reputable manufacturer.
- Intended Use: Consider how you plan to use your AR-15. For tactical applications, the benefits of side charging are more pronounced.
- Compatibility: Ensure the system is compatible with your existing lower receiver and other accessories.
Conclusion:
AR upper side charging offers a valuable alternative to traditional rear charging systems, providing distinct advantages in specific scenarios. By carefully weighing the pros and cons and considering your individual needs, you can determine if side charging is the right choice for your AR-15. Remember to prioritize quality components and proper installation for optimal performance and reliability. Always consult with a qualified gunsmith if you have any doubts or concerns regarding installation or modifications.
