Either way I turn the nut the range is either too high or too low (Noveske barrel and upper).
Would it make sense to lap the upper slightly to adjust the torque? From what I read above this sounds like a viable option. I've never liked the idea of a shim of any kind.
Also, do you know of a place where I can read about the proper procedure for lapping the receiver, since I've never attempted to do this before? Any help would be appreciated thank you.
