This is the original RIG Universal Gun Grease favored by shooters and gunsmiths alike as a superior lubricant and preservative. This clean, viscous grease is easy to apply to all your guns and provides absolute rust prevention during long-term storage. One thorough application of a thin film inside and out will protect your rifle, handgun, shotgun or muzzleloader against rust and corrosion. For full coverage, saturate a swab and run it back and forth through the barrel.
