I am working on a custom 6.5 Creedmoor build. I have not torn the donor rifle down as of yet so I am in able to swap parts around to test. My concern is this... I have a new CNC machined barrel nut and a new Apache barrel. I went to thread the barrel nut on and it seems excessively tight. I can only get it 2 or 3 revolutions before being unable to turn further. Has anyone else ran in to this? I don't want to force it and run in to problems. My others have all turned much easier.
