The solvent trap controversy comes against the backdrop of a national debate over how silencers should be regulated. At present, silencers fall under the National Firearms Act. An individual wishing to own one must fill out a special application with the ATF, pass a background check, submit fingerprints, and pay a $200 tax.

For those who do a lot of cleaning of their firearms they come in really handy in helping to prevent messes and capturing expensive cleaning fluids allowing them to be re-used.
Are solvent traps legal?
Yes. The ATF has classified solvent traps as “firearm accessories.” That means it is not a controlled item under any federal gun law.

What is the difference between solvent trap and silencer?
They have a distinct resemblance to silencers. The big difference is that solvent traps do not have a hole bored through the center and they do not have a serial number engraved on them. They are also not always designed to be shot.
Do I need an FFL or paperwork to buy a solvent trap?
No. Since the ATF has classified solvent traps as accessories, purchasing a kit is no different than buying any other commercial product online.

Declaration
The Bureau of Alcohol, Tobacco and Firearms considers a solvent trap a “Firearm Accessory”. The BATF recognizes that a Solvent Trap can be attached to the end of the barrel with an adapter, as a cleaning accessory and is not considered anything other than an accessory because a projectile, or bullet, cannot pass through the tube without modification. ANY modification to a product purchased from Wix24003.com voids the possibility of return or refund, and our refund & exchange policies are located on our Terms & Conditions and Refunds & Exchanges.
