What is an AR Side Charging BCG?
Understanding the Basics
The AR-15. It’s more than just a rifle; it’s a platform, a community, and a testament to American ingenuity. From its inception, the AR-15 has evolved, constantly adapting to the needs and desires of shooters across the globe. One area of continuous refinement has been the operating system, and specifically, the bolt carrier group or BCG. While the standard rear charging handle has served its purpose, a growing trend is changing the game: the AR Side Charging BCG. This article delves deep into the world of side charging BCGs, providing you with a complete understanding of their advantages, considerations, and how to select the right one for your needs.
The Standard BCG Explained
The foundation of any reliable AR-15 is its bolt carrier group. The BCG is the heart of the rifle’s cycling process, responsible for extracting spent casings, chambering new rounds, and ultimately, ensuring the rifle’s function. Within a standard AR-15, the BCG comprises several critical components: the bolt (which locks into the barrel extension), the bolt carrier (which houses the bolt and allows for its reciprocating motion), the firing pin (which strikes the primer), the extractor (which pulls the spent casing from the chamber), and various other springs, rings, and pins that work in harmony. The standard AR-15 utilizes a rear charging handle that’s attached to the upper receiver and typically works from the rear. When the handle is pulled, it moves the bolt carrier group rearward, compressing the buffer spring and cycling the weapon.
Side Charging Versus Rear Charging
Now, picture this: you’re shooting, and you’re wearing bulky gloves. Reaching back to grasp the charging handle feels awkward. You have a high-magnification scope, and the handle interferes with its placement or your eye relief. This is where the AR Side Charging BCG shines. It offers an alternative charging mechanism, usually located on the side of the upper receiver, providing a different approach to cycling the weapon.
How the Side Charging Mechanism Works
Unlike the standard rear charging handle, the side charging system allows for a more ergonomic and often faster manipulation of the rifle. With a side charging system, the handle typically extends from the side of the bolt carrier or is integrated directly into it. When pulled back, it directly engages the bolt carrier, completing the cycling process. This system opens up exciting possibilities for how you handle your rifle, allowing you to adapt your shooting style in new ways.
Benefits of an AR Side Charging BCG
Ergonomic Advantages
One of the biggest advantages that the AR Side Charging BCG offers is enhanced ergonomics. Side charging systems are especially beneficial for left-handed shooters, as they eliminate the awkward reach across the receiver. The ability to charge the rifle with your support hand, without contorting your body, can dramatically improve speed and comfort. This ease of access is important, as comfort translates to better control and accuracy.
Reduced Obstruction and Increased Space
Beyond the ergonomic benefits, side charging systems often provide more room on the top of the upper receiver. This additional space is a valuable commodity, especially when you’re mounting optics. The side charging handle can be designed to stay out of the sight picture, reducing the chance of interference. This becomes especially important if you’re using scopes, red dot sights, or other aiming devices that you need to attach.
Potential for Faster Reloads
Another significant benefit, though often debated, is the potential for faster reloads and reduced time to first shot. By charging the rifle with your support hand while maintaining your firing grip, you can potentially speed up the reload process. This might not be a huge change at first, but as you practice and adjust to your new method of charging, you may begin to notice a difference. Although improvements in reload speed often depend on the user’s training and practice, side-charging systems can certainly help improve the handling of a rifle.
Aesthetics and Customization
While the aesthetic appeal is subjective, the AR Side Charging BCG adds a distinct look to an AR-15 platform. Many side charging systems are available in a wide range of finishes and styles, offering users the ability to customize their rifles. Whether you prefer a tactical appearance or a more streamlined design, the side charging system is a great choice if you are looking to customize your rifle.
Considerations and Potential Drawbacks
Financial Investment
Of course, no system is without its drawbacks. When considering an AR Side Charging BCG, it’s essential to weigh the pros and cons. One of the first considerations is often cost. Compared to a standard BCG, side charging systems typically come at a higher price. The added design complexity and specialized manufacturing processes often contribute to the price increase.
Compatibility Challenges
Another key factor is compatibility. Side charging systems can have their own unique compatibility requirements. Before making a purchase, research whether the BCG will work with your existing upper receiver, lower receiver, and barrel. Ensure that the system is designed to fit and function correctly with all of your other components. It would be a frustrating experience to buy an expensive BCG only to find that it doesn’t work. Proper installation is critical for safe and reliable operation. Always follow the manufacturer’s instructions, and if you’re unsure, seek professional assistance.
Reliability Factors
The question of reliability often comes up in any discussion about AR modifications. It’s important to choose a side charging BCG from a reputable manufacturer that uses high-quality materials and follows precise manufacturing processes. However, as with any modification, there is a potential for reliability issues. In some cases, the added complexity of the system could potentially lead to malfunctions if the system is not properly maintained or designed.
The Learning Curve
There is also a learning curve. Switching to a side charging system will require some adjustment. It’s a good idea to be patient with yourself as you get used to the new method of charging the rifle. As you continue using the new method, you will become more proficient.
Maintenance Requirements
Maintenance is another factor to consider. While many side charging BCGs are designed to be as reliable and user-friendly as possible, some might require slightly different maintenance procedures compared to standard BCGs. Cleaning and lubricating the side charging mechanism may require extra attention. Always consult the manufacturer’s instructions for proper care.
