There is a lot of confusion surrounding the legality of gun silencers, but the answer is quite simple. In the United States, it is perfectly legal to purchase and use a gun silencer, as long as you follow the proper procedures.
There are two main ways to legally obtain a gun silencer in the United States. The first is to purchase one from a licensed dealer. You will need to fill out an ATF Form 4 and undergo a background check, just like you would for purchasing a firearm. The second way to legally obtain a gun silencer is to make one yourself, provided you have the proper paperwork and pay the associated tax.
Once you have obtained your gun silencer, there are some basic rules that you need to follow to use it legally. First, you must be 21 years of age or older to purchase a silencer. Second, you can only use the silencer on firearms that are lawfully owned by you. And finally, you must have the proper paperwork (ATF Form 4) with you whenever you transport the silencer.
With that said, some states have additional regulations surrounding the purchase and use of gun silencers. So, it’s always best to check with your local laws before buying or using one.
