Tipton's 13 Piece Solid Brass Jag Set is the fastest way to thoroughly clean, dry or oil the bore. Each jag is designed to provide a tight fit between the patch and the bore. A pointed tip keeps the patch centred and allows it to drop off when the jag exits the muzzle. Made with 8-32 threads (17 caliber has 5-40 threads), they will fit most brands of cleaning rods, and should provide years of service. The included storage box features marked cavities for each caliber.
