Otis Technology Small Caliber Cleaning Patches are a small but essential piece of any cleaning kit. Even the most expensive and effective cleaning rod is virtually useless without a patch to soak up solvent, apply lubricant and physically clean the interior of your firearm. Otis Tech knows this, which is why they've designed these 100% cotton cleaning patches with the same high standards they use on the rest of their cleaning kits. These Otis Technology cleaning tools can be used up to six times, making them a great value for multiple cleanings or multiple weapons. When attached to a cleaning rod with a slotted tip, Otis Small Caliber 100% Cotton Cleaning Pads create total 360 degree coverage because of their perfectly circular shape. These small cleaning patches are just 2 inches wide and were designed for.17 to.22 caliber rim fire weapons. To make your cleaning kit complete, purchase a set of Otis.17 to.22 Caliber Cleaning Patches. This cleaning accessory makes a great gift for the hunter or sport shooter in your life..
