One thing you will want to do, BEFORE sending in your receiver is to check with CS to make sure they HAVE the barrel(s) you want to have fitted in their inventory. bishopgrandpa must have ordered a barrel that is out of stock, and that may not be sceduled for production until February??? If your barrel is in stock, I would say 8-10 weeks at this time of year would be about right. This has to be their busiest time of the year, as far as the barrel program, not to mention they are trying to get the new 2007 production inventory up to speed. They still haven't got some of the 2006 3 barrel Combos ready yet.
