The Luth-ar BAA3-L16M 16" Lightweight Complete Upper Barrel Assembly brings together a 16-inch chrome moly vanadium barrel and a slim M-Lok handguard to create a responsive, easy-handling AR-15 upper. Built around an aluminum receiver with M4 feed ramps and a black hardcoat anodized finish, this complete upper is ready to pin onto your lower and head straight to the range.

This model is chambered in 5.56x45mm NATO with a 1:9" right-hand twist to stabilize a wide range of bullet weights. The lightweight profile barrel is threaded 1/2"x28 at the muzzle, giving you flexibility to install your preferred muzzle device or suppressor mount. An M-Lok compatible handguard offers generous real estate for lights, grips, and other accessories, while keeping weight down for extended training or competition sessions. Luth-ar’s attention to detail and proven AR components make this upper a solid choice for shooters who value reliability and clean machining.
