Tipton 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 centered 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. Convenient storage box features marked cavities for each caliber. 17 Caliber (5-40 threads) 338 / 8mm Caliber 20 Caliber (5-40 threads) 35 / 9mm Caliber 22 Caliber 375 Caliber 243 / 6mm Caliber 40 / 416 Caliber 25 / 6.5mm Caliber 44 Caliber 270 / 7mm Caliber 45 Caliber #239013 30 / 32 Caliber
