When used with a proper guide, having a stainless-steel cleaning rod won't mar your bore and will provide a solid cleaning tool for a lifetime. Sized for use in firearms starting from .22-caliber guns on up, these Shooter's Choice rifle-length, 36-inch cleaning rods are built durably and ensures that gun owners won't ever be without an effective tool to clean their guns. Each Shooter's Choice Rifle Cleaning Rod is made in the USA and features a full-size handle complete with steel ball bearings that allow the rod and a tight-fitting brush or jag to turn along with the barrel's rifling, so your threaded rod end won't come loose as it travels down the bore.
