Pro Shot Products Spear Tip 30 Caliber Jag - 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 our cleaning rods for a totally smooth fit. With Pro-Shot’s vast work and knowledge on manufacturing parts over the years, we developed what we like to call the Pro-Shot System. The Pro-Shot System is a simple superior solution: Use Pro-Shot’s cleaning rod, jag, and cleaning patches for a perfect fit every time you clean.
