The Swab-Its Bore-Tips Cleaning Swabs are unique foam swabs that are just the thing for giving your barrel a good cleaning. By utilizing a polyurethane foam molded over a polymer jag the Bore-Tips achieve a very tight fit in the bore. Additionally, Bore-Tips can be washed with soap and water and reused. The molded thread fits tightly and securely in to cleaning rods and can be removed and used again and again with no damage to the threads. Bore-Tips are available for several calibers and because they are foam and not cotton, they leave no fuzz or fibers behind. Also, because the foam swab is sponge-like it absorbs solvent and lube with less mess and makes complete contact with bore when passing through which ensures a completely coated bore. Attention: Do not use with ammonia-based solvents.
