Thanks for the knowledge! I really like that you mentioned my dear friend Anti-seeze....That stuff is a mechanics best friend (if you like saving your knuckles and don't like breaking bolts or sockets)...
Also, I wasn't aware that the barrel nut wrench had a spot for a torque wrench, as I haven't purchased that yet. That should make life very easy. It sounds like I need to purchase the barrel nut wrench, and make some blocks for a barrel vise...that'll save me a few buck over paying to have the barrrels swapped.
Thanks again!
