plt,
You say in Post 30 that when you undid the barrel nut the gas tube alignment changed. This sounds like the barrel is a loose fit in the receiver and even though you line everything up carefully, as you finally screw up the nut tight the barrel rotates slightly clockwise with the nut taking everything out of alignment. Do you think this might be the case?
What sort of barrel nut do you have? Is it the traditional MILSPEC type with multiple teeth that you have to line up with the gas tube hole, or is it a proprietary nut that comes with a particular handguard and has flats (so there's no teeth getting in the way of the gas tube).
