Does anyone know what the correct torque spec is for a castle nut on a carbine length buffer tube? ARMY TM 9-1005-319-23&P says that the spec is 40 FOOT-lbs when torquing a rifle length buffer tube but then says 40 INCH-lbs for the castle nut on a carbine tube. Consensus online seems to be that this is a typo and 40 ft-lbs is correct. Can someone confirm this?

Just get it tight.

If you want to stake knock yourself out. If you don't it won't hurt anything either unless you are really running the gun hard, then it may come loose but just tighten it back up.
