Description
RIG has been a mainstay on gun benches for generations, and this 12 oz jar is the workhorse size for anyone who takes care of more than one firearm. The formula blends carnauba, beeswax, and silicone into a preservative grease that clings to metal instead of running off or evaporating the way thin oils tend to. Wipe on a light film and it stays put, giving your steel a barrier against moisture, humidity, and the surface rust that creeps in during storage.
What Makes RIG Universal Gun Grease Worth Keeping Around
One of the reasons this stuff has stuck around so long is how little you need. A thin coat inside and out is enough to protect a rifle, handgun, shotgun, or muzzleloader, so a single jar covers a lot of ground before you make a dent in it. It works as both a lubricant on moving parts and a long-term preservative on exposed metal, which makes it handy whether you're doing routine cleaning or tucking guns away for the off-season.
Putting the 12 oz Jar of RIG Grease to Work
Apply it with a clean rag or a dedicated applicator, using just enough to leave a light, even film. Bores, bolt bodies, slide rails, hinge pins, and any bare metal that sees the elements are all fair game. The water-repellent film won't rub off as easily as an oil, so it holds up well on safe queens, hunting guns that live in damp blinds, and older collectible pieces where finish preservation matters.
The 12 oz jar size is aimed at folks who maintain a collection or run a home shop rather than someone looking for a range-bag tube. Buy it once and you've got a supply that'll outlast a whole lot of cleaning sessions.

Frequently Asked Questions
What does RIG Universal Gun Grease do?
It's both a lubricant and a rust preservative. A thin film keeps moisture off bare metal so rust and corrosion can't take hold, and it lubricates moving parts at the same time. It's a go-to for long-term storage as well as regular maintenance.
Can I use RIG grease on any type of firearm?
Yes. It's formulated to work on rifles, handguns, shotguns, and muzzleloaders. The same jar handles everything from a bolt gun to a revolver to an old blackpowder piece.
How much RIG grease should I apply?
Less than you'd think. The idea is a thin, even film wiped on with a rag or applicator, not a thick glob. A light coat inside and out is all it takes to protect the metal, which is why a 12 oz jar lasts a long time.
Will RIG grease run off or evaporate like oil?
No, that's one of its main advantages. The grease clings to metal and forms a water-repellent film that won't rub off the way thinner oils do. That makes it especially good for guns going into storage or living in damp conditions.
