The AR-15 platform's versatility is legendary, and a key part of that versatility comes from the ability to customize nearly every component. One popular modification that significantly alters the shooting experience is the side-charging bolt carrier group (BCG). This guide delves into the benefits, drawbacks, and considerations of using an AR-15 side charging BCG.
What is a Side Charging BCG?
Unlike a standard AR-15 BCG, which requires manipulating the charging handle located at the rear of the upper receiver, a side-charging BCG features a charging handle positioned on the side of the upper receiver. This seemingly small change can dramatically impact the shooter's experience, particularly in specific situations.
Advantages of a Side Charging BCG
Several compelling reasons exist for choosing a side-charging BCG for your AR-15 build:
-
Improved Ambidextrous Operation: The most significant advantage is enhanced ambidextrous functionality. Both left- and right-handed shooters can easily manipulate the charging handle without significant repositioning. This is especially beneficial for users who switch shooting stances frequently or operate in confined spaces.
-
Enhanced Use with Suppressors: Side chargers can be advantageous when using a suppressor. The reduced recoil impulse from the suppressor can sometimes lead to the charging handle failing to fully return to its locked position after firing. A side charger often provides more positive manipulation in such scenarios.
-
Improved Use in Certain Shooting Positions: Prone shooting, shooting from behind cover, or other positions that restrict access to the rear charging handle are made significantly easier with a side charger.
-
Potential for Increased Speed and Efficiency: Some shooters find the side charging handle allows for faster manipulations, contributing to quicker target acquisition and follow-up shots.
Disadvantages of a Side Charging BCG
While offering numerous benefits, side-charging BCGs also have drawbacks:
-
Increased Cost: Side-charging BCGs are typically more expensive than their standard counterparts due to the more complex manufacturing process.
-
Potential for Increased Complexity: The added mechanism can increase the complexity of the BCG, potentially leading to slightly higher maintenance requirements or a greater likelihood of malfunction if not properly maintained.
-
Potential for Reduced Reliability (in some cases): While reputable manufacturers produce high-quality side chargers, some designs might exhibit reliability issues, especially under harsh conditions or with specific ammunition types. Thorough research is vital before purchasing.
-
Ergonomics: The placement of the side charging handle might not be ideal for all hand sizes or shooting styles. Some shooters find it less comfortable or intuitive than a traditional rear charging handle.
Choosing the Right Side Charging BCG
Selecting the appropriate side-charging BCG requires careful consideration of several factors:
-
Reputation of the Manufacturer: Choosing a BCG from a reputable manufacturer ensures quality and reliability. Research reviews and seek recommendations from experienced AR-15 users.
-
Material and Construction: The BCG should be constructed from high-quality materials, such as properly heat-treated Carpenter 158 steel, for optimal durability and reliability.
-
Compatibility: Ensure the BCG is compatible with your specific upper receiver and other components.
-
Type of Charging Handle: Different designs offer varying levels of ease of use and durability. Consider the size, shape, and material of the charging handle to ensure a comfortable and secure grip.
Conclusion
The AR-15 side-charging BCG offers a compelling alternative to the traditional rear charging handle, particularly for shooters who prioritize ambidextrous operation, suppressor use, or specific shooting positions. However, potential downsides, such as increased cost and potential reliability concerns (depending on the manufacturer and design), warrant careful consideration before purchasing. Thorough research and careful selection from a reputable manufacturer are crucial to ensuring a positive experience with a side-charging BCG.
