You have to first fill out the NFA paperwork (which any licenced NFA dealer can help you out with). That'll take a couple months while it's scrutinised from the federal level down to the county level, but, once you get approval, you buy your silencer, pay the $200 transfer tax to the BATFE for your tax stamp, and have an NFA licenced firearms dealer receive it for you.
