Solid brass cleaning jags are 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. Kit includes 17, 22, 243/6mm, 25/6.5mm, 270/7mm, 30, 338/8mm, 35/9mm, 375, 40, 44 and 45 jags. Convenient storage box features marked cavities for each caliber.
