I would expect to wait 6-8 weeks if you order from a dealer that has never purchased from Robinson.
The XCR is a Hot Seller and Robinson ships to the dealers that have been with them from the beginning and have orders in the Que.
I waited 7-8 weeks and if I had it to do over again I would have bought mine from one of the Dealers mentioned in the where to buy section... Kermits... AIM or Clubster in SigForum actually advertised that he had a few with the New Gas System in stock 1400.00 shipped and insured.. you save sales tax but you have to get a FFL to do the transfer.. I found a dealer that does them for 25 bucks. ;D
I wish you luck..
