A Quick Look at the Side Charging Advantage
The AR platform. A name synonymous with adaptability, modularity, and customization. Within this realm, the AR-10 stands tall, a big-bore variant offering the punch of calibers like .308 Winchester and 6.5 Creedmoor. While the standard AR-10 upper receiver design remains a mainstay, another iteration exists to further enhance user experience. This is where the Side Charging AR10 Upper comes into play, an often-overlooked but significant upgrade for those seeking greater control and a unique edge. This comprehensive guide dives deep into the world of side charging AR10 uppers, exploring their benefits, features, considerations, and practical applications for the discerning firearm enthusiast.
Before delving into the specifics, let’s clarify the core difference. Traditional AR-10 uppers utilize a charging handle located at the rear of the receiver. While effective, it can present challenges. The Side Charging AR10 Upper, as its name suggests, places the charging handle on the side of the upper receiver, typically on the left-hand side. This seemingly minor shift unlocks a plethora of advantages for a wide range of shooters.
For those whose primary weapon is a right-handed shooter, the traditional rear charging handle can be operated with the support hand, which is slower and requires the shooter to break their firing grip to get the rifle running. The Side Charging AR10 Upper allows the shooter to manipulate the charging handle without removing the support hand from the handguard, potentially leading to faster and more efficient reloads. It also is better and quicker than working around a scope.
The benefits extend beyond mere speed. In tactical situations or when navigating thick brush, the convenience of a side charging mechanism becomes even more apparent. The charging handle’s location offers immediate access in scenarios where traditional charging methods might be obstructed.
Furthermore, those with optics mounted on their AR-10s will find that the Side Charging AR10 Upper simplifies operation, as it frees up the space behind the scope. This allows the shooter to keep a steady sight picture while manipulating the charging handle, which can be crucial in high-stress situations. This setup creates a more ergonomic and natural manual of arms.
Key Considerations When Selecting Your Upper
Choosing the right Side Charging AR10 Upper requires careful consideration of several crucial features. Understanding these elements ensures you select a receiver that perfectly complements your specific needs and shooting style.
The Charging Handle’s Design
The Charging Handle’s Design plays a significant role in the overall function of the rifle. The charging handle may be either reciprocating or non-reciprocating. With a reciprocating handle, the charging handle moves back and forth with the bolt carrier group during firing. Non-reciprocating handles remain stationary, improving the shooter’s line of sight. The choice ultimately depends on the shooter’s preference and intended use.
Material and Construction
Material choices are crucial. Most Side Charging AR10 Uppers are manufactured from either 7075-T6 aluminum or, more rarely, steel. Aluminum provides a good balance of strength, weight, and cost-effectiveness, while steel offers enhanced durability, potentially at the cost of extra weight. The manufacturing method (billet versus forged) further influences the upper’s characteristics. Billet uppers are machined from a solid block of metal, allowing for greater design flexibility and potentially tighter tolerances. Forged uppers, on the other hand, are created through a process that compresses the metal, enhancing its strength and resilience.
Compatibility
When evaluating compatibility, research which receiver your rifle will work well with. Always make sure the Side Charging AR10 Upper you choose is compatible with your AR-10 lower receiver. This includes checking the pattern, as AR-10 platforms come in a few major patterns. Further, consider the handguard and other accessories you will be utilizing. Compatibility ensures that all components work seamlessly together.
Gas System
The gas system must be matched to the barrel length and ammunition being used. The gas system’s length (rifle, mid-length, or carbine) directly impacts the rifle’s cycling. An adjustable gas block allows for fine-tuning to optimize performance and minimize issues like over-gassing or under-gassing. This adjustment can be an invaluable tool to keep a rifle working with different kinds of loads.
Barrel Considerations
The selection of the barrel, too, affects the overall accuracy. Consider the caliber, barrel length, and twist rate in relation to the intended use. Longer barrels generally provide greater accuracy and muzzle velocity, while shorter barrels enhance maneuverability. Twist rate refers to the rate at which the rifling grooves inside the barrel spin the bullet, which needs to be matched to the weight of the projectile.
Rail System
The rail system (handguard) dictates the type of accessories that can be attached. Various options exist, from the legacy Picatinny rail to the more modern M-LOK and KeyMod systems. M-LOK and KeyMod offer greater versatility and weight savings. Selecting the right rail system is a matter of personal preference and intended application.
Bolt Carrier Group (BCG)
The Bolt Carrier Group (BCG) is the heart of the rifle’s operating system. A high-quality, compatible BCG is essential for reliable function. Consider factors such as the material, finish, and overall construction quality. High-quality BCGs generally offer superior durability and smoother operation.
Budget
Finally, the budget plays a significant role. Side Charging AR10 Uppers are available across a wide price spectrum. While budget-friendly options exist, quality typically correlates with price. Investing in a well-made upper pays dividends in terms of performance, reliability, and longevity.
