The SAFE bore cleaner - for all calibers THIS LISTING IS FOR PISTOLS The PatchWorm Pocket Field Kit (PFK) is made entirely of durable nylon IN THE USA, and cannot harm the bore or muzzle crown. This universal cleaning kit is so compact, it fits comfortably in a shirt pocket. Pistol rods are 20" long from tip to head (not including the extra "tail" for easy extraction should the rod get stuck for any reason) and will clean up to 12" barrels. The pistol version comes with 7 color-coded cleaning heads: .20 cal (green) .22 cal (white) .243 - .284 cal (black) .308 - .348 cal (red) .355 - .40 cal (purple) .41 - .45 cal (orange) .50 - .54 cal (blue) The PFK comes with dozens of wet (with Ballistol Sportsman's Oil) and dry patches (7/8" diameter), suitable for all bore sizes through .35 caliber. Larger 1 1/4" diameter patches are available separately for the larger calibers. Reusable flip-lid containers are included for convenient storage. Fouling is most easily removed while the barrel is still warm. Slide on a cleaning head (green is permanently attached), pierce 1 wet patch, feed into chamber and pull straight from muzzle. Flip patch, pull again, remove wet patch. Pierce 1 dry patch, repeat. Where a range of calibers is specified for a cleaning head, a second patch can be added (stacked on top of the first) for the larger caliber to achieve a tight finishing stroke.
