Clenzoil Cobra Bore Cleaning System Features The Clenzoil Cobra Bore Cleaning System is built around an integrated bronze brush that loosens carbon fouling and lead deposits from the bore in a single pass. Following directly behind the brush a woven cotton braid collects the loosened debris before it can redeposit further down the barrel streamlining what is normally a multi step cleaning process. Used together with Clenzoil Field and Range solution the system is designed to deliver a more complete clean than a brush or patch alone. This combination tool approach saves time at the cleaning bench while still reaching the thorough result a dedicated cleaning routine demands. Sized for .38 .357 and 9mm bores the Cobra fits a range of common pistol and rifle chamberings that share similar bore diameters. Because the cotton braid and brush assembly is completely washable the tool can be cleaned and reused indefinitely rather than discarded after a single use like a disposable patch. That reusability makes it a cost effective addition to a regular maintenance routine for anyone who shoots these calibers often. This Clenzoil bore cleaning system is available for sale at GrabAGun for shooters who want a simple repeatable way to keep their firearms running clean.
