A solvent trap is a firearm cleaning system designed to capture cleaning solvent in order to be disposed of efficiently. It is an enclosed tube-shaped attachment that screws onto the end of a guns muzzle and traps solvents used during the cleaning of the guns barrel. Solvent traps are made to catch and prevent oil and solvent from dripping onto surfaces in your workspace. They are tubes made of materials such as aluminum and titanium, which are ideal for firearms cleaning. Solvent traps work by attaching to the threaded end of the barrel where the muzzle brake or suppressor usually screws onto. The solvent trap consists of a metal tube that is closed at the end furthest from the barrel. The enclosed end is either permanently closed or has a threaded cap that seals the end of the tube. Solvent traps are legal in the United States and do not meet the definition of a silencer or suppressor under federal law. They can be used to clean a firearm to avoid a mess. However, it is important to note that using a solvent trap as a suppressor is illegal and can pose a huge threat to your equipment and personal safety.
