Six months is correct. I picked up my Smith Enterprise Wind Talker 556 can on Wednesday. My paperwork was sent June 22nd, my check cashed June 25th, I went pending July 7th, my stamp was approved December 5th, and the stamp arrived December 12th.
So then yours was quicker than 6 months, closer to 5 months.
