Pro-Shot’s Benchrest Quality spear tip brass jag keeps the cleaning patch in place running through the bore. The most efficient and effective way to clean a bore is with a jag draped with a patch that completely covers the bore. This reduces cleaning time and provides a superior clean barrel. Pro-Shot designs each jag to match up with their cleaning rods for a totally smooth fit. The Pro-Shot System is a simple superior solution: Use this cleaning rod, jag, and cleaning patches for a perfect fit every time you clean!
