Does anyone calculate the actual torque applied using a formula or calculator like this one www.belknaptools.com/support-library/extensions-calculator/
I'm wondering if the TM torque range of 30-80 ftlbs takes into account the length of the armorers wrench and torque wrench. Any thoughts? |

Maybe someone who is a high end builder....maybe.
Mostly the shaved ape turns the wrench until the barrel nut is "tight". Then turns it until the next lug lines up to insert the gas tube. Shaved ape job done. Someone decided to doccument the instructions in a manual; 30 lbs was not tight enough and above 80 lbs was too tight. That way, when the shaved ape got it wrong, it was already written down and he could officially get into trouble. 
Seriously though, that is an interesting point in the quest to get rifles built in a uniform manner to get good accuracy and performance. |

Any thoughts? The torque range is correct for USGI wrench standoff distance and torque wrench placed in line with USGI wrench. |
