1) Choosing an AR-15 Receiver
When it comes to building your perfect AR-15, the receiver is arguably the most important part to consider. This component houses the firing mechanism and is the foundation of the rifle. It’s crucial to select a quality receiver to ensure your firearm operates efficiently and accurately.

When choosing your AR-15 receiver, be sure to consider the size and weight of the receiver, as well as compatibility with other AR 15 parts you plan on using.

2) Selecting an AR-15 Barrel
When it comes to building your perfect AR-15, selecting the right barrel is a crucial step in the process. At 80-lower.com, we offer a wide range of AR-15 barrels to meet your specific needs and preferences.
First and foremost, it’s important to consider the length of the barrel. A shorter barrel is ideal for close-quarters combat, while a longer barrel can provide increased accuracy for longer-range shooting. The most common lengths for AR-15 barrels are 16 and 18 inches, but you can also find shorter or longer options depending on your needs.
Next, you’ll want to consider the caliber of your barrel. The AR-15 is compatible with a variety of calibers, including .223, 5.56mm, 300 Blackout, and 6.5 Grendel, just to name a few. It’s important to choose the right caliber for your specific shooting needs and preferences.
Another important factor to consider is the material of your barrel. Stainless steel and chrome-lined barrels are both popular options, as they provide increased durability and corrosion resistance. You can also find lightweight options made from carbon fiber or aluminum.
At 80-lower.com, we offer a wide range of AR-15 barrels made from high-quality materials to ensure optimal performance and longevity. Whether you’re a beginner or an experienced shooter, we have the perfect barrel for your AR-15 build.
3) Optics for Your AR-15
One of the most critical components of any AR-15 build is the optics system. There are numerous factors to consider when choosing optics for your rifle, including accuracy, range, and visibility. Here are some options to help you make the best decision for your AR-15 build.
Red Dot Sight
A red dot sight is a great option for close-range shooting, providing rapid target acquisition and fast tracking. This type of sight does not magnify your target, so it may not be the best choice for long-range shooting.
Holographic sights are similar to red dot sights, but they project a holographic image onto a glass lens, making it easier to aim accurately. These sights offer quick target acquisition, a wider field of view, and excellent accuracy at close range.
Magnified optics come in different power levels and are ideal for long-range shooting, giving you the ability to see targets farther away and aim accurately. You can choose from fixed power scopes or variable power scopes, depending on your preference and the type of shooting you plan to do.
Night vision optics allow you to see and aim in low-light or no-light conditions, making it an excellent option for hunting or tactical shooting. Night vision scopes use infrared light to illuminate your target, allowing you to see them even in complete darkness.
Regardless of which optics system you choose, be sure to select high-quality American-made optics that are durable and reliable. Invest in the best optics system you can afford, as it will make a significant impact on the accuracy and performance of your AR-15 build.
