I have seen a lot of information bouncing around about this, I have held off publishing any information until I spoke to some others in the business and done a little digging, This is what I have learned.
Republicans introduced the Duncan-Carter Hearing Protection Act, delivered by GOP sponsors U.S. Rep. Jeff Duncan of South Carolina and Rep. John Carter of Texas, to remove silencers from National Firearms Act regulation and treat them as regular firearms, so they would be able to be transferred via background check and Form 4473. Included in the bill would refund the $200 tax stamps paid since 10-22-2015
Beginning in 1934, the Federal government has regulated devices designed to suppress the report of firearms as Title II devices that required registration under the National Firearms Registration. Putting forth as law if you were to buy or manufacture a silencer requires the permission of the BATF in the form of extensive paperwork, wait times, and a $200 tax. Regulating silencers in such a way seems pointless to many and deregulating would certainly boost the gun industry. A similar bill was introduced last year but fail to be passed. Now with a much more pro Second Amendment president and majorities in the house and senate the chances are much better. The current bill is awaiting committee assignment.
