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!
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.
