I am rebarreling a rifle with a URX4 handguard. I was able to get the gas block and handguard off without issue, but now having a problem re-installing it.
With 3 shims (I don't remember # of notches) I would need probably 90-100 ft-lbs of torque to properly time it. If I remove the smallest shim, it overclocks. Is 100 ft-lbs of torque acceptable for the URX4? What is the range it calls out?
I first installed it 3 years ago so I don't have the instructions. The smallest shim I have is 1 notch.
