The PatchWorm .177 cal Cleaning Kit for RIFLES is made entirely of durable nylon IN THE USA, and cannot harm the bore or muzzle crown. This cleaning kit is so compact, it disappears in a shirt pocket. It is perfect for those tiny bores in .17 cal rimfire, centerfire and airguns. Rifle rods are 36" from tip to head (not including the extra "tail" for easy extraction should the rod get stuck for any reason). Includes a dozen dry 7/8" round cotton flannel patches in a reusable flip-lid storage container. Fouling is most easily removed while the barrel is still warm. Pierce 1 wet patch, feed into chamber and pull straight from muzzle. Flip patch, pull again, remove wet patch. Pierce 1 dry patch, repeat. We offer a combined shipping rate when you assemble a cart prior to payment.
