AR-15 Lower Kits
AR-15 Lower Receivers Kits form the heart of any custom AR build. These components are the foundation upon which the rest of the rifle is built, making them one of the most important parts of an AR-15. The AR lower houses the fire control group and magazine well and provides the mounting points for the stock and upper receiver. To complete the lower, you'll need an AR 15 lower parts kit, which typically includes components like the trigger assembly, safety selector and takedown pins. It's worth keeping in mind that the AR 15 lower receiver is the serialized part of the firearm, meaning it's the component that's regulated by law and requires a background check for purchase.
AR-15 Uppers Kits
The AR-15 upper receivers kit contains essential components that house the bolt carrier group, barrel and handguard, all vital to the functionality of the rifle. The AR uppers connect directly to the lower receivers, creating the core framework of the AR-15.
