I have a brand new Aero Precision M4E1 Complete Upper receiver in OD Green Cerakote. I was going to build a new upper but plans have changed so I just need to move it. Asking $120 obo I live in New Port Richey and work in Clearwater Thanks for looking and if add is up than it is still available. Check out my other listing for a brand new Ballistic Advantage 13.9 barrel also.
