Upgrading your platform with a complete upper receiver is the most efficient way to change calibers or performance specs. Because uppers are not considered firearms, they require no FFL transfer and ship directly to your door.

At Brigade Manufacturing, every complete AR-15 upper and 9mm upper is factory-assembled and test-fired. We verify headspacing and cycling on every unit to ensure 100% reliability out of the box.

Our uppers are forged from 7075-T6 aluminum and feature our patented U-LOK handguard system. This unique rail design is compatible with both M-LOK and Keymod accessories, offering unmatched modularity.

Whether you need a 5.56 NATO, .300 Blackout, or 7.62x39 upper, our builds are backed by a Lifetime Warranty. Experience the quality of a manufacturer-direct upper designed for mission-critical performance.
