Today, I went to field strip the Bolt Carrier Group to clean it and once I got the spring and that long pin removed (I don't know the name) I went to separate the bolt carrier rails from the body of the bolt, but they only traveled to the end of the main body and stopped. In other words they seem to have a stop, preventing me from separating them.
Now the very end of the rails seem slightly rough and maybe could stand a very, very light filing to smooth them and perhaps then they would separate. The ends are ever so slightly galled. Could this be the problem?
Also, if I can't separate the rails, will it be a problem in functioning properly? As it is, if I can's separate the rails, I'll have no trouble cleaning.
