NFA transfers are different than normal handgun or rifle transfers. To transfer a Suppressor, Machinegun or the like, you have to have ATF approval and pay a $200 tax stamp for each item you wish to transfer. This process involves a sign-off by your local Chief Law Enforcement Official, background check by BATFE and, as stated above, the $200 transfer tax. This process usually takes from 6 weeks up to 1 year.
