Thread: Just some truing videos and pics

So what are you actually doing? Facing off the surface the bolt lugs run on, re-cutting the thread and facing the receiver face that the barrel or recoil lug sits on in one setup to ensure it is all square/concentric? Then cutting a thread on the barrel to match the now oversize receiver?

Do you do anything to the bolt side of the receiver to ensure the bolt is concentric and the lugs are square to the axis as well?

Yep. Then bolt face and lugs. Do nose to just to true it up to center line so the recess in the barrel is matched up easier
