Hi Don, I've wondered about the results of what I just did for years! It seemed that no one had a tried and true barrel torque sequence, that a shade tree machinist like me could understand....
... But, when I hit the 50ft. pounds of torque, the back up and reset to hand tight dimension was the same on every barrel, every time...
.... so, what can one take away from this? If you are installing a luger barrel, and it comes up to anywhere from .125" to .100" left for indexing, you might have to tighten and loosen a few time to get indexed, (or use up the crush?) but it will be between 35 and 50 ft. lbs when you get it lined up! Any more than .125" or really even .100" and you might have to relieve the flange or horse it back and forth a few times to stretch everything in or out... (not recommended!...
) Last little bit of new found wisdom, if, when you bust it back loose... if you hear a metallic squeak! You are on the road for disaster???.... Stop and regroup and collect weapons and ammo... as your going to have a battle on your hands from there on out! ... Best to all, til...lat'r...GT...
