I am in the final stages of building my ar. Everything is assembled and loosely hand tightened to make sure it all fits and I am ready to start torquing everything to spec. I have seen quite a few posts on this and other forums where people use loctite blue in various spots but these are also usually the people who hand tighten the hell out of everything and don't use a torque wrench. If I torque everything to spec is there any reason for loctite on anything or are there places I should use it anyway just to be safe? Wanna kill these ads? We can help!
