Not a complete upper - Aero Precision AR15 16in 5.56 Complete Upper Receiver with Flash Hider w/Magpul MOE Handguard

When I think of a complete upper, I think ready to attach to a lower and fire away. Not this one. Luckily, I looked at the photo and was prepared. No bolt carrier, bolt, or charging handle. Not even the forward sling loop(it fits, I put one on it). It’s not a bad upper, if you realize it’s not a complete upper. It’s a good start.
