Gas blocks get bedded per recommendations from Bill Alexander after he fleet-tested his initial rifles. I also bed the gas tubes and ensure proper alignment with the tube and the carrier key. Then there are all the torque specs for muzzle devices ( I want as low of a torque value as possible at the muzzle per AMU lessons-learned), barrel nut torque (different for barrel weight), and scope rings.

Is the gas block betting for accuracy? What is the procedure, and do you also pin it? If you use green retaining compound do you consider this a permanent installation or do you have a method to remove that?

I have read that gas tubes self-seal with carbon after a bit of use. Is that incorrect, or is that bedding for something other than sealing?

How do you select barrel nut torque?
