Thanks for the ideas. I took it apart and going to back together. I also have an Aero upper, ME4 enhanced and it is very difficult to get the Barrel into the receiver. I contacted Aero because the feed ramps of the barrel are not flush with the feed ramps cutouts of the receiver. The best I can tell there is about 0.01 to 0.02 space/ledge left for the barrel to be flush with receiver.
My first email with Aero, they said that not all barrel feed ramps fit flush with the receiver. I have not built a lot of ARs but everyone that I have both feed ramps and cut outs have always been flush. With that amount of difference I wonder about headspacing too. [ATTACH=CONFIG]11404[/ATTACH]
