I was visiting the gun show in Souix Falls on Saturday and picked up a brochure for SDSilencers, http://www.sdsilencer.com/, I noticed their brochure had the simple steps for obtaining a silencer,

select silencer

fill out paperwork

obtain law enforcement signature

get fingerprinted

paste photos on forms

pay $200 transfer tax to BATFE

wait for paperwork to clear

fill out ATF form 4473

take your silencer home

My question is if this is made in SD and sold to a SD resident then would it be expempt from the federal firearms laws per the freedom firearms act? I was unable to talk to anybody about this but it caught my attention.

I am sure they wouldn't risk their federal firearms license for the state law but it does seem to be a conflict,
