Rifle Uppers

Rifle uppers are an essential component of any AR-15 build, providing the foundation for accuracy, reliability, and overall performance. Designed to connect directly with your rifle lower receiver, these uppers house the barrel, bolt carrier group, and other critical parts that define how your rifle shoots. With longer barrel lengths than pistol uppers, rifle uppers are perfect for precision shooting, hunting, and long-range performance while maintaining the trusted versatility of the AR platform.

At AR15-Overstock.com, we offer a wide selection of AR rifle uppers, including complete assemblies, stripped uppers, and individual upper parts. Our inventory features a variety of barrel lengths, calibers, and handguard styles to help you build the exact rifle you want. Whether you’re upgrading an existing rifle or starting a brand-new build, the right rifle upper makes all the difference.
