Armory Labs CPL-9 Gun Care cleans, protects and lubricates all firearms, from low-caliber hand guns to fully automatic rifles. Unlike other ordinary gun cleaners and gun lubricants, CPL-9 sticks effectively to metal providing a protective coating that repels moisture and inhibits corrosion in both high and low temperatures while never getting sticky or tacky. This ability to repel moisture makes CPL-9 ideal for outdoor use protecting against dirt and water, even in the rain. Also, since CPL-9 bonds to metal as a very light coating, it does not sling off in semi-automatic or automatic actions. As a gun cleaner, the low viscosity allows CPL-9 to penetrate through fouling to reach the metal lifting out dirt for easy removal while leaving that protective coating that not only protects against corrosion on the entire weapon but also makes future cleanings easier and more effective, it even eliminates the pesky "crust ring" that plagues muzzleloaders. Additionally, CPL-9 as a gun cleaner and protectant decreases fouling even after thousands of rounds providing long lasting performance, and has been reported to increase time between jams in .22 caliber pistols as well increasing muzzle velocity. Using CPL-9 on mechanisms and bores both lubricates and protects better and longer than gun lubricants fortified with PTFE. CPL-9 is also safe on plastic, rubber, and painted surfaces. This ensures that it will not damage your grips or other surfaces that you may get the product on. Additionally, some have used CPL-9 not only on their firearms but also on their reloading equipment.
