jrkarp Posted December 3, 2007 Share Posted December 3, 2007 I just purchased one of the pre-ban M3 police trade in topfolders that CMMG is selling. These weapons had been converted by the police department to semi auto only. I ordered the part to convert it back to its original configuration. Tonight, I took the gun apart and installed the new selector. I thought I had done everything right, including winding the selector return spring back around the selector and everything else. Now, I can't get the gun to switch to semi-auto. It works as a pump (although the bolt does not come forward with the slide - is that normal?), but an attempt to switch it to semi results in the return spring sending the selector back to pump. Does anyone know what I am doing wrong? Did I reinstall something incorrectly? I was very careful. Quote Link to comment Share on other sites More sharing options...
