These 12 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.
