I use blue loctite on the threaded spring detent retaining screw, "for the rear take down pin behind the back plate" I install on every receiver I build. I use blue loctite on, trigger guard screws, receiver tension screws, barrel bedding, hand guard screws, etc. I have used red loctite on gas block mounting screws, but have switched to Rocksett. I use green loctite"620" between the barrel and gas block block journal for proper seal, barrel bedding, between the gas key and bolt carrier instead of Permatex aviation gasket compound and to seal gas tubes to gas blocks.
If I had known this I would have bought stock in Loctite.
