Breakthrough Clean Square Patches Features Breakthrough Clean Square Patches are woven from 100% cotton knit material a fabric chosen for its ability to absorb solvents oils and fouling without falling apart during use. The pre-cut square shape measures 1.5 inches per side sized to fit cleaning rods built for .243 through .270 caliber bores. Because each patch is already cut to size there is no need to trim material before use saving time during routine maintenance. The woven construction holds together well when pushed through a bore reducing the chance of a patch tearing and becoming lodged in the barrel. This pack includes 600 individual patches a supply large enough to last through many cleaning sessions before running low. The patches are housed in a plastic tray that keeps them contained and protected from dirt while in storage making it easy to pull one out whenever needed. A tray of this size suits gunsmiths range regulars and hunters who clean multiple firearms on a consistent basis. For anyone looking to keep a well-stocked cleaning kit Breakthrough Clean Square Patches are available for sale at GrabAGun.
