| I just finished building two Romy kits from a flat, now I have a problem with both of them. Sometimes the bolt carrier gets stick when I pull the charging handle back, sometimes it doesn't. It usually gets stuck in the same place. When I checked for function before installing the barrel, it was as smooth as glass. Now that the barrels are installed, I have this little problem on both of them. Am I missing something? I should also note that I have not yet installed the FCG, so I know it's not catching up on that. |

First, have you lubricated the bolt lugs and the rails? If not, try that. There could be just enough added friction to cause a stoppage.
If you get the stoppage with the parts lubricated, take the bolt out of the carrier and slide it along the lower rails into the trunnion, then reverse the process. If the top of the lower rails are too high, you should be able to feel the bolt drop slightly when it enters the trunnion and feel any resistance when it moves out of the trunnion. |
