AMSOIL 100% Synthetic Firearm Lubricant and Protectant
AMSOIL 100% Synthetic Firearm Lubricant and Protectant is a purpose-built synthetic lubricant formulated for the moving parts on rifles, handguns, shotguns, and black powder guns. The action, bolt, and hinge surfaces inside any firearm have to be cleaned and lubricated to stay reliable, and a dedicated synthetic lubricant outperforms the all-in-one cleaner-lubricant-protectant blends that compromise performance for the sake of a single bottle on the shelf.
Hunters and sport shooters routinely run their guns after long storage, after sitting through wet and humid weather, or on remote trips with no opportunity for a daily cleaning. AMSOIL Synthetic Firearm Lubricant was developed and tested in the AMSOIL chemical lab and in the field across a variety of common range and hunting firearms to deliver outstanding protection in those demanding conditions. The result is a lubricant film that stays in place on metal surfaces, performs across hot and cold operating temperatures, and helps prevent the blockage, jams, and wear that can sideline a firearm at the wrong moment.
Why a dedicated synthetic firearm lubricant matters
An all-in-one cleaner-lubricant-protectant tries to do three jobs from one bottle and gives up performance in each role. AMSOIL splits the job between two purpose-built products, AMSOIL Firearm Cleaner for fouling and powder residue removal, and AMSOIL Synthetic Firearm Lubricant and Protectant for the lubrication step that follows. The lubricant is formulated specifically for firearms rather than borrowed from a general-purpose oil, so the film thickness, additive package, and corrosion-resistance behavior are dialed in for action surfaces, bolt rails, firing pins, springs, and trigger mechanisms.
The synthetic chemistry stays fluid in cold weather and resists thermal breakdown when a barrel and action heat up during sustained range sessions. Compatibility was verified across the metals, woods, composites, and rubbers commonly found on modern and classic firearms, so the same lubricant can run from a stainless slide on a striker-fired pistol to the wood furniture and steel barrel of a shotgun without finish or seal concerns.
Verified corrosion protection
AMSOIL Data Bulletin G3430 documents two industry-recognized corrosion screens. In Salt Fog testing per ASTM B117, surfaces protected with AMSOIL Synthetic Firearm Lubricant showed no corrosion while a leading competitor product allowed visible rust on the same test panel. In Humidity testing per ASTM D1748, AMSOIL Firearm Cleaner showed no corrosion as well, demonstrating that the cleaner does not strip protection between the time a firearm is wiped down and the next lubricant application.
Range testing reinforced the lab data. After firing one hundred rounds through a shotgun, a single cleaning pass with AMSOIL Firearm Cleaner removed powder residue and left a smooth, clean bore. AMSOIL Synthetic Firearm Lubricant then provided the lubrication that kept the action working consistently through additional rigorous range cycles across multiple firearm types.
Recommended applications
AMSOIL 100% Synthetic Firearm Lubricant is recommended for use on:
- Rifles, including bolt-action, lever-action, semi-auto, and modern sporting rifles
- Handguns, including striker-fired pistols, single-action and double-action revolvers, and 1911-pattern pistols
- Shotguns, including pump, semi-auto, over-and-under, and side-by-side designs
- Black powder guns, where corrosion protection is especially important after a shooting session
How to apply
The product is supplied in two ready-to-use formats so the same lubricant chemistry can be applied with either a precise drop-by-drop bottle or a broader aerosol spray. Before any service, ensure the firearm is unloaded. Shake the container well prior to use. Begin by cleaning the firearm with AMSOIL Firearm Cleaner per the firearm manufacturer recommendations, then apply AMSOIL Synthetic Firearm Lubricant evenly to all metal parts including barrels, bolts, firing pins, springs, and trigger mechanisms. Finish by applying a thin layer to the exterior surfaces of the firearm to leave a corrosion-resistant film for storage between range sessions.
Aerosols may have different disposal requirements than other household waste in some jurisdictions. Dispose of the empty container and any unused contents in accordance with all federal, state or provincial, and local regulations.
Available sizes and product codes
AMSOIL Synthetic Firearm Lubricant is offered in a 4 oz. precision bottle (FLPBA-EA) for fine application and a 5 oz. spray can (FLPSC-EA) for broader coverage. The spray can is also available in a Case of 12 (FLPSC-CA) for shops, ranges, and households that go through the spray format regularly. The 5 oz. spray can is not currently distributed in Canada. AMSOIL Firearm Cleaner, the companion product, is available in 8 oz. bottles and 5 oz. spray cans, with the spray can not currently distributed in California.

Frequently asked questions
Is AMSOIL 100% Synthetic Firearm Lubricant a CLP product?
No. CLP stands for cleaner-lubricant-protectant, a single-bottle approach. AMSOIL splits the job into two purpose-built products. AMSOIL Firearm Cleaner does the cleaning and powder-residue removal step, and AMSOIL Synthetic Firearm Lubricant and Protectant does the lubrication and ongoing corrosion-protection step. The split-bottle approach lets each formula deliver dedicated performance instead of compromising in the name of convenience.
What temperature range does the lubricant cover?
AMSOIL Data Bulletin G3430 describes outstanding protection and performance in both hot and cold climates and does not publish a specific minimum or maximum operating temperature. The synthetic chemistry is designed to stay fluid in cold weather and to resist thermal breakdown when a barrel and action heat up during a sustained shooting session.
Is it safe on wood stocks, polymer frames, and rubber grips?
Yes. The Data Bulletin states the product is safe to use on all metals, woods, composites, and rubbers commonly found in firearms. The same lubricant can move from a polymer-frame striker-fired pistol to the wood furniture of a classic shotgun without finish, seal, or stock concerns.
Why use AMSOIL Firearm Cleaner before the lubricant instead of just spraying lubricant on dirty parts?
Powder fouling, copper residue, and old lubricant trap moisture and abrasive particles against metal surfaces. Lubricating over that residue locks in the contamination instead of removing it. Cleaning first with AMSOIL Firearm Cleaner removes the residue, then applying AMSOIL Synthetic Firearm Lubricant places a fresh lubricant film directly on clean metal where it can do its job.
Does the spray can fit hard-to-reach internal parts?
The 5 oz. spray can is designed for broader coverage on bolts, slide rails, and exterior surfaces. The 4 oz. bottle (FLPBA-EA) is the better choice for placing a precise drop on a firing pin channel, sear surface, or other internal point where the spray pattern would be too wide. Many owners keep both formats on the bench for that reason.
How much lubricant should be applied?
Apply the lubricant evenly to all metal parts including barrels, bolts, firing pins, springs, and trigger mechanisms, then finish with a thin layer on the exterior surfaces. Heavy over-application is not necessary, can attract dust and debris in the field, and can migrate onto ammunition or unintended surfaces. A thin, even film is the goal for both function and corrosion protection.
Why is the 5 oz. spray can not available in Canada?
Aerosol regulations vary by jurisdiction. AMSOIL Data Bulletin G3430 confirms that the 5 oz. spray can format of the lubricant is not currently distributed in Canada, while the 4 oz. bottle remains available. AMSOIL Firearm Cleaner, the companion product, is also not distributed in Canada at this time, and its spray can format is not distributed in California.
