Over the last several years I have been messing around with an M4gery upper of unknown orgin (Gun show) that has no markings on it. I have posted here several times and have had great advise. I have learned a lot about the AR system messing around with this. Am I an expert now? Heck no ! I did finally send the upper to M1S and they changed the bolt and regauged and thought it should be alright. It's not. I have decided that I am going to buy a new upper to put on the Bushmaster lower. Question, Model one sales upper? RRA? or Bushmaster? I don't want to get burned again and spend lots of time and ammo trying to make it right. What do all of you think I should do?
