The AERO PRECISION AR15 5.56 16in Complete Upper Receiver is a ready addition to any high-quality AR-15 project. The mil-spec upper receiver includes a forward assist and ejection port door. This upper also includes a Magpul MOE SL handguard with M-LOK slots for the optional addition of accessories of your choice.
This complete upper does not include a bolt carrier group or charging handle, but once you’ve added those parts as well as a complete lower receiver, you’ll be ready to slap steel and punch through paper. Aero Precision are one of the premier names in AR-15 parts and components, and Aero’s complete uppers are yet another example of their dedication to quality.
