Are there any non-obvious spots to dremel down, or did you just lengthen the track the charging rod travels on?
If there are other spots, could you possibly point them out? My charging rod bent, and straightening didn't work too well.
IIRC correctly there were 3 spots total, the slot where the rod goes through and a couple inside. I can't remember exactly where they were, it took some experimenting to figure it out. I believe they were on the right side of the gun. That rod is really easy to replace, it should be easy to find something at a hardware store that'll work.
