sandtrap Posted July 23, 2016 Report Share Posted July 23, 2016 Fitted a new 15" hand gaurd and the barrel nut is the type with cut outs for a gas tube and the hand gaurd has slots to match up . Made up to 42nm (30ftlbs) to line up the slots . I think 30ftlbs is to low but feel that if I torque until the next slot lines up then torque could be high .. I think 80ftlbs is the absolute max that should be applyed So the question , is 30ftlbs enough ? I suppose I just need to shoot and see if it's ok ?

Tenex Posted July 23, 2016 Report Share Posted July 23, 2016 I believe the torque for that particular guard is @ 35ft lbs Link to comment Share on other sites More sharing options...

bradders Posted July 23, 2016 Report Share Posted July 23, 2016 You're worrying too much about nothing. Tighten ut up to where you feel it is tight enough to stay on. Don't worry about Torque specs just tighten it up to where the grooves/holes line up and be done. If it's too hard to get round to the next slot then use copper grease on the threads. You'd be surprised how much you can hang off the wrench on a AR upper receiver Link to comment Share on other sites More sharing options...
