I can't get the damn thing off for anything and have buggered up the castle nut at this point. Yes I am using the correct wrench but this thing won't budge!
Edit:
Finally got the thing off, and no evidence of any locktight. Not sure what the torque specs are, but that was the toughest one I have ever done. Now I am going to have to get a new nut, but at least I got the thing off

I found mine to be easier than other ARs. The SR-15 castle nut isn't even staked, let alone loctited.
Wait until you get a hold of an RRA. My SR15 was cake compared to that.
