Cleaning the barrel on your rifle or pistol can be a messy choir. Solvent splatter, drips and dirty patches always seem to end up where you don't want them. Strong solvents and powder residue can stain clothes and work surfaces. This Patch Trap puts an end to the mess. Threaded 1/2x28 as well as a threadless 1/2" hole version. Other end is threaded to accept empty amphibious reptile sounding named sports drink bottle to catch the patches and solvent. Enjoy.
