No loctite on the barrel nut. The buffer tube castle nut should be staked. Some people prefer to not stake the castle nut because it's easier to remove in case someone wants to change the end plate/sling adaptor or something later on. Some use a little blue loctite on the castle nut to secure it, some apply nothing. It either comes loose or it will stay on tight forever, it's a gamble. Are you running an standard A2 front sight tower or an screw clamp on type gas block/sight?
