Ammonia-free formula works fast to dissolve and strip out stubborn copper fouling caused by high-velocity, copper-jacketed bullets used in varmint, tactical, and competition guns. Helps restore accuracy to neglected bores and conditions the steel to reduce future copper buildup. Won’t etch or pit barrel steel, but should not be used on brass, aluminum, and blued or plated surfaces. Odorless, environmentally safe, biodegradable, non-toxic, and non-flammable - just like M-Pro 7 Gun Cleaner.
