I got a New Haven by Mossberg 679 lever action in .30-.30 from GB about a month or so ago and when I received it the sub-receiver was cracked and it needed a new extractor. So I managed to get the thing apart without damaging anything and replaced all parts needed... then I went off to JRTC in Ft. Polk.... came back and can't seem to get the damn thing together. I really don't want to pay $60-70hrs to have someone put it back together when I probably can figure it out in the long run with some help. Any information would be great. Thanks.
