Basically I just had a quick question, finishing another build and wanted to be sure on something. I understand when you assemble the new bbl to the new upper you are suppose to tighten/loosen 3 times to prepare the receiver threads. Is this necessary if you are just reassembling an old barrel to a used upper? Basically is the "tighten/loosen 3 times" mainly for new receivers or just to try help alignment? On some of my other rifles that have seen more than one barrel I just tighten the bbl nut up to spec.

You could do it to be cautious but, you'll probably be good if its used. I believe it is done to stretch the threads to help seat the barrel to the receiver. Do it, whats 45 extra seconds....and don't forget to at least grease the threads
