What is a Solvent Trap? A solvent trap is a firearm cleaning system that traps byproduct created during the cleaning process. As gun owners ourselves, we understand the difficulties surrounding maintaining, cleaning, and accessorizing your guns. Here at Solvent Trap USA, we strive to educate the gun community in the USA on solvent traps, gun cleaning, gun accessories, and ATF forms 1 and 4. Our solvent trap kits and parts are made here in the USA, and we serve the entire United States with their solvent trap needs! We are excited to produce new solvent trap designs that will last a life time.
