Jeff,
I received my CMMG 16" Middy Upper today that I had ordered through Aim Surplus. I was a smiling guy until I realized I couldn't shut the Ejection Port Dust Cover. The spring loaded nipple works fine, but the milling on the actual upper that keeps it shut isn't done to spec. It needs a little more milling to make it shut and work properly. In fact, I can press the hell out of it and it wont snap shut. So, I called AIM and they said to send it back and wait for a new one to come in. (I laughed) Or, I could call CMMG and see if they could fix it. Well, I called you guys and left a message with customer service, but haven't gotten a return call. What should I do here? Thanks in advance for your attention. EDIT: Just got a call from CMMG. I believe a rubber mallet and a few cycles will do the trick. Sorry for the newbie question. Learning as this is my first AR. |

I have had similar problems with a few uppers lately. Maybe in the mad rush to turn out pats the suppliers are not doing as well as they could.
I have found that most of these get better with age. Maybe they just have sharp corners on them and it makes it a bit more difficult to snap that ball over that lip. I have never considered sending one back. Normally its a quick and easy task to just smooth it out and let it break in. No worries. Good luck with yours. |
| That's how mine is and it came to me with the detent assembly on the ejection port door partially ripped out of the door itself. I just emailed CMMG and told them I needed a new door assembly and they said they would ship it out. Even once I replace the door it probably will still be tight but I'm sure it will wear in. |
