I put copper bearing anti-seize on them and use the tighten/loosen, repeat, to get them to >30 <80 ft lbs, depending upon where the gas tube hole aligns. Never had one come loose and that included my 300 WSSM AR 15 upper. That thing made a 450b seem like a 6.5 Grendel by comparison. Great for clearing out the shooting benches on either side of me.

im with hoot - i'd never loctite a barrel nut on. they can be SOB enough to remove without it sometimes. save the loctite for places its needed - like scope ring screws
