The AR-15 platform's versatility is legendary, and nowhere is this more evident than in the variety of charging handle options available. While the standard rear charging handle works perfectly well for most shooters, the side charging upper receiver/bolt carrier group (BCG) combo offers a compelling alternative with distinct advantages and disadvantages. This guide dives deep into the world of side charging AR-15 uppers, exploring their benefits, drawbacks, and considerations for choosing the right setup for your needs.
Understanding the Advantages of a Side Charging AR-15
The primary benefit of a side charging upper is its enhanced functionality in specific scenarios. Here's a breakdown:
-
Improved Ergonomics for Suppressed Shooting: When using a suppressor, the added length and gas blowback can make manipulating a traditional rear charging handle difficult and potentially uncomfortable. A side charging handle eliminates this problem, allowing for smoother operation without interfering with the suppressor.
-
Enhanced Ambidextrous Operation: Side charging handles inherently offer ambidextrous functionality, benefiting both right-handed and left-handed shooters. This is particularly useful in tactical situations where quick manipulation is crucial.
-
Better Accessibility with Certain Accessories: Certain optic setups, large handguards, or other accessories can obstruct access to the rear charging handle. A side charger bypasses these obstructions.
-
Use in Close-Quarters Combat (CQB): In tight spaces where the weapon's position relative to the shooter is restricted, a side charging handle allows for manipulation without the need for major adjustments to shooting posture.
The Potential Drawbacks of Side Charging Systems
While side chargers offer significant advantages, it's crucial to acknowledge potential drawbacks:
-
Increased Cost: Side charging upper receivers and BCGs generally cost more than their standard counterparts. The added machining and design complexity contribute to the higher price point.
-
Potential for Reliability Issues: Some side charging systems have faced criticism regarding reliability, particularly in harsh conditions or with certain ammunition types. However, reputable manufacturers have addressed many of these early concerns through design improvements. It's crucial to choose a high-quality system from a trusted manufacturer.
-
Increased Complexity: The added mechanics of a side charging system can potentially introduce more points of failure compared to a standard system. Regular cleaning and maintenance are essential for optimal performance.
-
Weight: Side charging uppers and BCGs can slightly increase the overall weight of the firearm.
Choosing the Right Side Charging Upper Receiver/BCG Combo
Selecting the ideal side charging setup involves careful consideration of several factors:
-
Manufacturer Reputation: Choose a reputable manufacturer with a proven track record of producing high-quality, reliable AR-15 components. Research reviews and seek recommendations from experienced AR-15 users.
-
Material Quality: The materials used in the upper receiver and BCG directly impact durability and longevity. Opt for components constructed from high-quality materials such as properly heat-treated steel and aircraft-grade aluminum.
-
Compatibility: Ensure that the side charging upper receiver and BCG are compatible with your existing lower receiver and other components. Check specifications carefully to avoid incompatibility issues.
-
Intended Use: Consider the primary purpose of your AR-15. If it's primarily for home defense, suppressed shooting, or tactical applications, a side charging system might be advantageous. For recreational shooting, a standard charging handle might suffice.
Conclusion: Weighing the Pros and Cons
Side charging AR-15 upper receivers and BCG combos present a compelling option for shooters who value specific advantages, such as improved ergonomics for suppressed shooting or enhanced ambidextrous operation. However, potential drawbacks, such as increased cost and potential reliability concerns, must be carefully considered. By thoroughly researching manufacturers, understanding the implications, and choosing high-quality components, you can make an informed decision about whether a side charging system is the right choice for your AR-15 build.
