Torque on an ar barrel is overrated, I torque then turn to the next gas tube hole.. Did you lube the threads? with what? did you seat the threads before the final torque? Do you have another barrel you can test?
The barrel is not too heavy unless the upper is cracked, then it does not matter.
My rifle and pistol are tools, I am the weapon.
