Alright, well, I have a Deep Fire M4 that I have disassembled to where the only thing I need to remove is the gearbox itself from the lower receiver. I've removed every pin I can find that keeps the gearbox in place, but I can't seem to get the dang thing out. What I need it out for is to replace the selector switch which has somehow snapped right off. Also, just as a side note, there is the rear body pin that holds the upper and lower together on the real steel that looks like it goes through the gear box, but I can't seem to remove that no matter now much force I put on it. Anyways, if any of you are familiar with one of these, mind helping me out? I'll post pictures if I can find a camera that doesn't take shit pictures.
Thanks.
