Birchwood Casey Moly Lube is a fast-drying dry-film lubricant for moving metal components in firearms and precision airguns.
Birchwood Casey Moly Lube is a fast-drying dry-film lubricant for moving metal components in firearms and precision airguns. Its aerosol solvent evaporates quickly, leaving molybdenum-disulfide particles on the metal to form a smooth, extremely slippery lubricating film. The dry surface reduces friction and wear without attracting dust, dirt and other contamination like a wet oil film can. Suitable for use Internal moving metal components in firearms Pistols, rifles and shotguns Metal sliding and friction surfaces Actions and other moving firearm components Mating metal surfaces exposed to high pressure Components where wet oil may collect contamination Firearms used in dry or dusty environments Precision airguns where petroleum lubricants are not recommended Firearm-maintenance workshops Why choose Birchwood Casey Moly Lube? Forms a dry and extremely slippery film on metal Molybdenum-disulfide particles reduce friction Helps improve wear resistance Suitable for surfaces exposed to extreme temperatures and pressures Penetrates between mating metal surfaces Carrier solvent dries almost instantly Dry film does not attract dust and dirt Suitable for internal moving firearm components Recommended by the manufacturer for precision airguns Aerosol application covers complex-shaped components Technical specifications Product type: Dry-film firearm lubricant Container type: Aerosol Volume: 280 ml Solid lubricant: Molybdenum disulfide Molybdenum-disulfide content: 1–5% according to the safety data sheet Carrier: Fast-evaporating solvent Drying: Almost instantaneous Resulting surface: Smooth, dry and extremely slippery Primary application: Internal moving firearm metal components Additional application: Precision airguns Primary functions: Lubrication, friction reduction and wear protection Resistance: Suitable for high-temperature and high-pressure contact surfaces Attraction of dust and dirt: Low Application: Aerosol spray Rust protection: Not the product’s primary function Hazard classification: Extremely flammable aerosol Container: Pressurized and may burst if heated Working environment: Outdoors or in a well-ventilated area Storage: Cool, well-ventilated location below 50 °C Supplied with Birchwood Casey Moly Lube dry-film lubricant aerosol, 280 ml Frequently asked questions How does a dry-film lubricant differ from ordinary gun oil? Moly Lube’s liquid carrier evaporates quickly and leaves a dry lubricating film containing molybdenum disulfide. Unlike a wet oil coating, the dry surface is less likely to collect dust, dirt and firing residue. Which firearm components can be treated? The product is intended primarily for internal moving metal components and sliding or friction surfaces. Apply it only to parts for which lubrication is specified in the firearm manual. Is Moly Lube suitable for airguns? Yes. The manufacturer recommends it for precision airguns where petroleum lubricants are not advised. Do not apply it inside a spring-piston airgun’s compression chamber or onto seals unless expressly instructed by the airgun manufacturer, as unsuitable lubrication can cause dieseling or damage. Does Moly Lube protect against rust? Its primary purpose is friction and wear reduction rather than long-term corrosion protection. Use a separate gun oil or rust protectant on exterior metal and firearms placed in storage. How should the surface be prepared? Remove old oil, grease and dirt, then allow the component to dry completely. A clean, degreased metal surface helps the dry film form evenly and adhere properly. How should Moly Lube be applied? Confirm that the firearm is completely unloaded and remove ammunition from the working area. Disassemble it according to its manual, clean the metal parts requiring lubrication and apply a thin, even coat. Allow the carrier solvent to evaporate fully before reassembly. Can it be used inside the barrel? It is not a bore cleaner or bore-storage treatment. Avoid applying it to the chamber or bore unless expressly specified by the firearm manufacturer. Before firing, the chamber and barrel must be dry and free from obstructions. Can the aerosol be used on wood, plastic or optics? The product is intended for metal surfaces. Avoid contact with wood, plastic, rubber, seals, painted finishes, optical lenses and electronic components unless compatibility has been confirmed. For controlled application, spray it onto a cloth or applicator first. What safety precautions are required? The product is an extremely flammable aerosol, and its pressurized container may burst if heated. Use it outdoors or in a well-ventilated area, avoid breathing vapour or spray, and wear protective gloves and eye protection. Keep it away from heat, sparks, flames and children. When is Birchwood Casey Moly Lube the right choice? Moly Lube is suitable when internal moving metal components require a dry, low-friction lubricating film. It is particularly useful in dry or dusty conditions where wet oil could collect dirt and firing residue. It is also suitable for precision airguns when the manufacturer does not recommend petroleum-based lubrication. A liquid gun oil may be a better choice for exterior rust protection and components designed for conventional oil lubrication. Expert recommendation Dry-film performance depends on proper surface preparation. Remove old oil and contamination, allow the metal to dry and apply the thinnest practical coating. A heavy layer does not improve lubrication and may affect the fit or movement of closely fitted components. Do not apply the lubricant to trigger-engagement surfaces, the chamber, bore, ammunition or an airgun compression chamber without express manufacturer instructions. After the film has dried, check manually that all moving components operate freely and that the safety functions correctly. Dry lubrication without an oil film that collects dirt Birchwood Casey Moly Lube leaves a dry, smooth and extremely slippery molybdenum-disulfide film on metal. It reduces friction and wear on moving components and is well suited to applications where wet oil could attract dust and contamination.
