You might want to get this too so you can mount it in the vise, hand tighten barrel to upper. Then set it in the attached tool with the barrel pointing toward the floor. http://www.brownells.com/gunsmith-tools-...od468.aspx
Insert the tool thru the upper and lock it in the barrel extension. Torque to 30 lbs, then turn until the gas port lines up. Pretty easy with this tool, I wish I had bought one a year ago.
