after installing a carbine handguard on the AR, i scratched up the barrel nut pretty bad...took some coating off it and was wondering if this was no big deal or if i should repaint some of it to prevent future rusting

Only a $6 part. I personally wouldn't worry about at all unless it bothers you :)
