What do you torque your barrel nut to? I've tried numerous times to reach the middle to high side of the specs but I can't get the nut much above 35-40 ft lbs before the teeth start breaking on the nut or the wrench breaks. I've been tightening it as much as possible till the gas tube hole lines up and then I go test fire it. This method worked on the BM upper I took to the sand box. |

tacked thread up above that reads...headspace,torque values and barrel break-in i have yet to use a torque wrench on any of my builds. this is what i do. torque to yield loosen tighten loosen tighten loosen tighten line up next slot if its not already. |
| Apply moly lube to the barrel nut's threads. Torque it to 30#. If the gas tube will not clear a notch in the barrel nut, tighten more until it will. If you cannot align it without exceeding 80#, loosen and tighten it a few times, as this will lower the overall torque value. |
