Scotty,
Unusual that in 18-80lbs a gap does not line up for the gas tube. I have heard of people going to 85lbs but don't go any higher or the aluminium will start to deform.
For something as important as the barrel-receiver interface I would stick carefully within the recommended range 35-80lbs. I cut off a tooth once and it worked. You don't need all 20 teeth to get the barrel nut on and off, and they are only there to aid assembly. One missing tooth will do absolutely nothing to anything, except let you fit that gas tube properly. Plus, you won't see the missing tooth once the handguard goes on.
As for what torque, 35-40lbs is what manufacturers of non-teeth handguards are recommending, but not less than 35lbs - and definitely not 18lbs.
