I had to send my brand new weapon in because the buffer tube broke while extending the Magpul stock. S&W called and said the weapon is fixed but they had to replace the reciever which gave it a new serial number. Now they won't send it back to me, they insist on sending it to a licensed dealer who wants to charge me a $35.00 transaction fee. I know it's not a ton of money but come on man, at least suck up the dealer charge S&W.
