For my 2nd order, stamp #5, check was cashed on July 9th, 2018 and I received stamp and approval on April 26th, 2019. Definitely quicker than the first order. My 3rd order checks were cashed on 3-27-2019 so I hope to have them by New Years.
I have to say that my purchases, specifically paperwork and finger prints, thru the Silencer Shop via one of their kiosk units is the best thing I ever did. They may not have access to every can made, but the process is super easy and quick.
