These 13 solid brass cleaning jags are the fastest way to thoroughly clean, dry, or oil the bore of your firearm. 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.Features : Solid Brass Tight Fit Between Patch and Bore Hinged Box with Marked Cavities
