Also, 150 ft. lbs. of torque for barrel extension to barrel supports that I sure as heck didn't over-torque the EFAB when clocking it at 10:30-11:00 for final wrenching, ~ 20 ft. lbs., all while using the Geissele RR. For this particular 6.5G build, I used an ALG defense rail with their shim kit; barrel nut torque most likely did not exceed 55 ft. lbs.
For those interested, here is an interesting discussion about barrel extension/barrel separation. Some of the comments were made by people in the barrel manufacturing industry.

55 ft lbs? Dang that's like ridicules too high amount of torque.
Accuwasher, locktite and time it by hand with less then 10 inch pounds is perfect. I can't see putting more torque on the muzzle then it takes too tighten the barrel nut.
The barrel is a lever. You put 55 foot lbs on the tip there is no telling how much your putting on the extention.
