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. A stripped lower receiver is just the basic frame, while a complete lower receiver includes all the necessary components, such as the trigger group and buffer tube.
Next, you’ll need to choose an upper receiver. Like lower receivers, upper receivers come in stripped and complete varieties. The upper receiver houses the bolt carrier group, barrel, and handguard, so it’s important to choose one that fits your needs and preferences. Consider factors such as material, weight, and rail system when selecting an upper receiver.
Once you have your lower and upper receivers, it’s time to choose a barrel. Barrels come in various lengths, profiles, and materials, so it’s essential to select one that suits your intended use for the rifle. For example, a longer barrel may be better for long-range shooting, while a shorter barrel is more maneuverable in close quarters.
After selecting a barrel, you’ll need to choose a bolt carrier group (BCG). The BCG is responsible for cycling the rifle and chambering new rounds, so it’s crucial to choose a high-quality BCG that will function reliably. Consider factors such as material, coating, and staking when selecting a BCG.
Next, you’ll need to choose a handguard. Handguards come in various lengths and styles, such as free-floating and drop-in. Free-floating handguards are generally considered more accurate, while drop-in handguards are easier to install. Consider factors such as weight, rail system, and attachment points when selecting a handguard.
Once you have your lower and upper receivers, barrel, BCG, and handguard, it’s time to choose a stock. Stocks come in various styles, such as fixed, collapsible, and adjustable. Consider factors such as length of pull, cheek weld, and material when selecting a stock.
Finally, you’ll need to choose a trigger group. Triggers come in various styles, such as single-stage and two-stage. A good trigger can greatly improve the accuracy and performance of your AR-15, so it’s important to choose one that fits your shooting style.

In conclusion, building your own AR-15 is a fun and rewarding experience that allows you to customize your rifle to your exact specifications. By choosing the right components for your build, you can create a rifle that is tailored to your needs and preferences. So take your time, do your research, and enjoy the process of building your own AR-15.
