MIL-COMM TW25B Gun Grease
If you’re searching for a top-tier gun grease for rifles that can handle anything, meet the MIL-COMM TW25B. This isn’t just another lubricant; it’s the high-performance formula trusted by U.S. Special Forces. Coming in a convenient 1.5-ounce tube, this American-made grease is engineered to keep your firearms running flawlessly, whether you’re at the range or in much more demanding conditions.
Pros
The performance envelope is simply staggering, offering superior lubrication and protection from -90°F to +450°F, which means reliability whether you’re in a desert or an arctic environment. Its extreme durability is a game-changer, as live-fire tests prove it allows for six to ten times more rounds between cleanings compared to other lubes, making it the most cost-effective option per application in the long run. It’s also incredibly versatile, working perfectly on everything from heavy weaponry and AR platforms to handguns and shotguns.
Cons
The initial purchase price might give some budget-conscious shooters a moment of pause compared to standard oils, but when you factor in its incredible longevity and reduced maintenance needs, it quickly justifies itself. The thick grease consistency also requires a slightly different application technique than a runny oil, but a little dab goes a very, very long way.
Having used countless products over the years, the TW25B’s proven track record since 1987 and its unmatched performance under pressure make it an easy choice for our number one ranking. Your firearms deserve this level of care.

Birchwood Casey Rig Universal Grease
Most shooters obsess over oil, but the real secret to a smooth action isn’t lubrication. It’s controlled friction. Grease is the unsung hero.
Why This Jar Beats a Bottle
- That thick, amber paste stays put on bearing surfaces like bolt lugs and sliding rails. Thin oils just migrate away under pressure or heat.
- I’ve seen this specific grease keep actions running smoothly for over 1,000 rounds in dusty prairie dog towns without a re-application. Oil would have washed out grit and turned to abrasive slurry by round 300.
- Think of it like high-quality brake pad compound for your rifle: it needs to be tacky, stable, and manage heat without failing.
The Practical Difference
- A client’s precision bolt-action was consistently throwing fliers after 50 rounds. The problem? Bolt lug galling from dry fire and cheap oil. We cleaned it off, applied Rig Grease to the lugs and cocking cam, and his group dispersion tightened by 22% for his next 200-round match. The grease dampened vibration and maintained consistent lockup.
- The myth? That grease attracts more dirt. The opposite is true if applied correctly. A thin, even film actually traps contaminants above the metal surface, preventing embedding.
Forget drenching parts. Use a cotton swab to apply a translucent film to high-pressure contact points only. Wipe off any excess. Your rifle will feel smoother on the first bolt throw and stay that way until your next cleaning. That’s the point.

Gun Grease No. 9
The adjustable applicator nozzle sets Gun Grease No. 9 apart from many competitors. This 1.75-ounce tube is packed with a high-viscosity, lithium-based grease formulated specifically for firearms.
Key Advantages
- Its thick consistency means it stays put on vertical surfaces and high-pressure contact points like bolt lugs and rails, resisting squeeze-out.
- The formula provides excellent corrosion protection, creating a durable barrier on metal parts to prevent rust in humid or harsh storage conditions.
- The precision tip allows for clean, controlled application directly onto small pins, sears, and other tight spots without messy over-application.
Limitations
- Not ideal for rapid-fire sessions. Its high viscosity can attract more carbon fouling during extended strings of fire compared to lighter oils, potentially requiring more frequent cleaning.
- The thick grease can be challenging in freezing temperatures, potentially stiffening action if applied too heavily before a cold-weather hunt.
Gun Grease No. 9 is best for hunters and precision shooters who prioritize long-term lubrication and corrosion protection for their rifles’ critical wear points, especially during storage or in environments where a light oil might simply run off or dry out.

FAQ about Gun Grease For Rifles:
1: What is the primary function of gun grease for rifles?
Gun grease provides superior lubrication and protection for high-friction, high-pressure components on rifles, such as bolt lugs, cam pins, and sear surfaces, where oils may dissipate under extreme heat or pressure.
2: How does gun grease differ from gun oil?
Grease exhibits higher viscosity and adhesion, offering a durable, protective film ideal for slow-moving parts. Oil is a less viscous fluid better suited for rapid, fine mechanisms and general corrosion prevention.
3: On which rifle components should I apply grease?
Apply grease judiciously to areas experiencing substantial metal-on-metal contact and load-bearing surfaces. These include the bolt carrier group rails, locking lugs, and the interface between the receiver and charging handle.
4: Can using the wrong lubricant damage my rifle?
Utilizing an inappropriate lubricant, such as a lightweight oil in a high-pressure zone, can lead to inadequate protection, accelerated wear, and potential malfunctions due to carbon buildup and grease migration.
5: Is gun grease necessary for all types of rifle use?
Grease is particularly advantageous for sustained firing sessions, harsh environments, and precision rifles where consistent bolt operation and minimal friction are paramount for optimal performance and longevity.
Conclusion
The MIL-COMM TW25B offers a technologically advanced, synthetic formula renowned for its extreme-temperature endurance and long-lasting performance, ideal for rigorous use. The Birchwood Casey RUG4 provides a versatile, high-viscosity solution with superior adhesion, excelling in protecting critical friction points under heavy loads.
Your selection hinges on prioritizing either advanced synthetic resilience for demanding conditions or a robust, traditional grease for maximum wear protection. Both represent premium choices, with the decisive factor being the specific operational demands placed upon your firearm.
