In the next couple of days I will be doing my first barrel swap. I have all the tools on hand and the stock barrel is already off. Have watched a couple of Utube videos and still uncertain. The following are my areas of concern:

1. Should I remove the extractor and ejector for final fit? No problem if necessary as I have a new kit coming.
2. After I install the "GO" gauge, is where I have real concern. Do I close the bolt on the "GO" gauge and finish screwing the barrel until it stops? If so, do I back off the, "touch" a small bit and then try the bolt? Do I thread the barrel in/out until I get a small amount of bolt pressure or do I adjust the barrel until there is no pressure when I work the bolt? I hope this question is understandable.
3. How much torque is necessary on the barrel? Thanks
