So on my Bushmaster xm-15 I have been trying to get the castle nut off to put an ASAP on, and its near impossible. I don't think there is locktight on it, but i have no idea, has anyone else experienced this? if so how have you been successful in getting it off? I have been using a TAPCO 3 prong and it will not budge at all, even started tapping the wrench with a hammer for leverage, but still nothing. I am afraid I am going to start to either dent the threads, or tear up the nut at this point.
