Choosing the Right Components for Your AR-15 Build
Building your own AR-15 can be a rewarding and fulfilling experience for any gun enthusiast. Not only do you get to customize your rifle to your exact specifications, but you also gain a deeper understanding of how the firearm works. However, before you can start assembling your AR-15, you need to choose the right components for your build.
The first step in building your AR-15 is selecting a lower receiver. This is the part of the rifle that is legally considered the firearm, so it must be purchased through a licensed dealer. Lower receivers come in two types: stripped and complete. Stripped lower receivers are just the basic frame of the rifle, while complete lower receivers come with all the necessary components already installed. If you’re new to building AR-15s, a complete lower receiver might be the best option for you.
Next, you’ll need to choose an upper receiver. The upper receiver houses the barrel, bolt carrier group, and other key components of the rifle. Like lower receivers, upper receivers come in stripped and complete varieties. If you’re looking to customize your rifle with a specific barrel length or handguard, a stripped upper receiver might be the way to go. However, if you want a more straightforward build, a complete upper receiver is a good choice.
Once you have your lower and upper receivers selected, it’s time to choose a barrel. Barrels come in various lengths, materials, and profiles, so it’s essential to consider what type of shooting you’ll be doing with your AR-15. If you’re planning on using your rifle for long-range shooting, a heavy barrel with a longer length might be the best option. On the other hand, if you’re looking for a lightweight and maneuverable rifle, a shorter and thinner barrel might be more suitable.
After selecting a barrel, you’ll need to choose a bolt carrier group (BCG). The BCG is responsible for loading, firing, and ejecting rounds from the rifle. When choosing a BCG, it’s crucial to consider the material, coating, and design of the bolt carrier. A high-quality BCG can improve the reliability and performance of your AR-15.
Next, you’ll need to select a handguard for your rifle. Handguards come in various lengths and styles, including free-floating and drop-in designs. Free-floating handguards are typically more accurate and allow for better customization, while drop-in handguards are easier to install and more budget-friendly. Consider your shooting style and preferences when choosing a handguard for your AR-15 build.
Finally, you’ll need to select a stock and grip for your rifle. Stocks come in various styles, including fixed, collapsible, and adjustable options. Grips also come in different materials and designs, so it’s essential to choose one that feels comfortable and secure in your hand. Remember to consider ergonomics and shooting comfort when selecting a stock and grip for your AR-15.
In conclusion, choosing the right components for your AR-15 build is crucial to creating a rifle that meets your needs and preferences. By carefully selecting a lower and upper receiver, barrel, bolt carrier group, handguard, stock, and grip, you can build a customized AR-15 that is tailored to your shooting style. Take your time researching and selecting each component to ensure a successful and enjoyable build process. Happy building!
