Upper Build Kits

What are AR-15 Upper Build Kits?

AR-15 upper build kits are sets of components that allow you to build or customize the upper receiver of an AR-15 rifle. The upper receiver is the part of the rifle that houses the barrel, bolt carrier group, and charging handle. It is responsible for chambering, firing, and ejecting rounds. By building or customizing your own upper receiver, you can tailor the rifle to your specific shooting needs and preferences.

Calibers and Lengths

One of the main features that you can choose when building or customizing an AR-15 upper receiver is the caliber. The AR-15 platform is designed to be chambered in a variety of calibers, including 5.56x45mm NATO, .223 Remington, and .300 Blackout, among others. Each caliber has its own set of characteristics and performance attributes, so it's important to choose the one that best meets your needs. In addition to caliber, you can also choose the length of the barrel on your AR-15 upper receiver. Barrel length can affect the accuracy and velocity of the rifle, as well as its overall size and weight. Common barrel lengths for AR-15s range from 7.5 inches to 24 inches, with popular choices being around 16 inches for general use and 20 inches for long-range shooting.

Benefits of Building Your Own AR-15 Upper

Building your own AR-15 upper receiver has a number of benefits. First and foremost, it allows you to customize the rifle to your specific shooting needs and preferences. You can choose the caliber, barrel length, and other components that best suit your intended use for the rifle. In addition, building your own upper receiver can also be a rewarding and educational experience. It allows you to learn about the various components of the rifle and how they work together, which can be a great way to gain a deeper understanding and appreciation for firearms. Finally, building your own upper receiver can also be a cost-effective option compared to buying a pre-assembled upper. By purchasing the components separately and assembling them yourself, you can often save money and end up with a rifle that is tailored to your specific needs and preferences.
