Lapping project - trying this out

[lazyengineer]

Was the barrel nut torque the same for both pre lapped and post lapped? What was the barrel nut torque?

I think so but didnt write it down and don't remember. In my experience, barrel nut torque hasn't historically matered a lot. In the classic world of high power service rifle and traditional barrel nuts, one would be forced to torque all over the incredibly wide range of appropriate torques from build to build, to get the gas tube lined up. And it never seemed to matter much.
