Some people are nervous about owning a solvent trap to clean firearms. Those who feel this way obviously just want to make sure they are abiding by the law, but with a little research into the facts they will find it is 100 percent legal to own a solvent trap to clean your firearms. Again,It is 100 percent legal to own a solvent trap kit to clean your firearms. The BATF, 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 as anything other than an accessory because a projectile, or bullet, cannot pass through the tube without modification. This means the solvent traps can be purchased and sold without any paperwork or an NFA tax stamp. You do not need a Form 1 to purchase a Solvent Trap. However if you turn a solvent trap into a Suppressor without filing and receiving back an approved Form 1 you are committing a crime that could be punishable as a felony. You MUST have the tax stamp in hand before making any modifications. Failure to do so is a violation of Federal Law. We are not responsible for your actions should you fail to do this and we DO NOT recommend or condone ANY modifications to our products. So long as your solvent trap continues to be used to catch cleaning fluids and debris, you are completely legal without concern. As a solvent trap owner, you are solely responsible for what you do with your solvent trap. If you do decide to modify the trap for anything but a cleaning aid, it is a strong recommendation you read and follow the BATF regulations on NFA items. Please see ATF Form 1 Online for any other to apply for a form one or read any BATF regulations on NFA items.
