Accuracy fixed.

I did mine verticle but basically just like this with a couple paper towels.

Put the barrel in vertical, cleaned the dripping stuff and put on the barrel nut to hold in place for 24 hours.

What I noticed with his liberal application of blue, most comes off when he slid the barrel in the receiver, seems to me an thin application of blue in the receiver and on the ext. would be better. That said, while he wiped blue off the threads it didn't appear he used any grease on threads prior to torquing the nut so it's likely that nut with be a pain to remove if that day ever comes as there has to be some lock-tite on the threading.

Personally a barrel fit such as that really should have a shim as that fit is what I'd call sloppy.
