AR Upper Receivers | Complete AR15, AR10 & AR9 Uppers
Upgrade, customize, or finish your rifle build with our premium AR upper receivers. Whether you’re building a new AR or upgrading your current rifle, our complete AR15 uppers and AR10 uppers are designed for reliable performance and a perfect fit with your compatible lower receiver.
What Is an Upper Receiver?
An AR upper receiver is the top half of your AR platform rifle and contains the critical components that make your firearm function. Depending on the configuration, it can include the barrel, bolt carrier group (BCG), charging handle, handguard, and muzzle device.
Pairing the right upper with your lower determines your rifle’s caliber, barrel length, and performance. Swapping uppers is one of the easiest ways to customize your AR or experiment with new calibers without purchasing a completely new firearm.
Complete AR Uppers for Every Build
We offer complete AR upper receivers in multiple calibers and configurations, perfect for:
-
AR15 Uppers: 5.56 NATO / .223 Wylde, .300 Blackout
-
AR9 Uppers: 9mm pistol-caliber carbines
-
AR10 Uppers: .308 WIN and 6.5 Creedmoor for long-range precision
Every upper is ready to mount to your lower receiver, making it easy to finish your build or upgrade your current rifle.

Our upper receivers come in a variety of configurations to fit your shooting style:
-
