Clocking that last nth amount of barrel nut ...
3rd build, have read all Sweeny's and Own all Zediker's books on ARs and know enough to run up the barrel but and back off a few times to help seat the final attempt to achieve the required torque.
This build was just adding a 15" key mod railed forend ($55 from Delta Team Tactical) in place of the free-floated carbine forend, but the nut would not budge once 'tight'. I ended up 'dressing' the ends of the threads, just removing any color with a few strokes of a diamond stone.
But there was NO WAY otherwise that I would have seated it to the next gas tube alignment hole above the minimum required torque otherwise.
What says the more experienced builders? What tips do others have to offer?
