Step-by-Step Guide

How to Clean and Lubricate Your Firearm with AMSOIL

A field-strip-and-clean routine using AMSOIL Firearm Cleaner and Protectant (FCP) and AMSOIL Synthetic Firearm Lubricant & Protectant (FLP). Always confirm the firearm is unloaded before disassembly.

1
Clear and disassemble the firearm
Confirm the firearm is unloaded — remove the magazine, lock the action open, and visually and physically inspect the chamber. Field-strip per the owner's manual: bolt carrier group and charging handle from an AR-15, slide / barrel / recoil spring from a semi-auto pistol, bolt from a bolt-action rifle.
2
Apply AMSOIL Firearm Cleaner and Protectant
Spray AMSOIL Firearm Cleaner and Protectant (FCP) onto the bolt carrier group, bolt face, chamber, and slide rails. Let it dwell for 30–60 seconds to dissolve carbon fouling and powder residue. For the bore, run a wet patch through, follow with a bronze brush, then alternate patches until they come out clean.
3
Wipe down and dry all parts
Use clean microfiber or cotton patches to wipe carbon, copper, and cleaner residue off every surface. AMSOIL FCP leaves a light protective film — wipe wear surfaces (rails, lugs, bolt) clean before applying lubricant so the lube layer goes on bare metal.
4
Apply AMSOIL Firearm Lubricant & Protectant
Apply a thin, even film of AMSOIL Synthetic Firearm Lubricant & Protectant to wear surfaces: AR-15 bolt carrier rails, cam pin, bolt lugs and gas rings; pistol slide rails, barrel hood, lugs and barrel/bushing contact; bolt-action lugs and bolt body. A light film outperforms heavy oil — wipe any excess.
5
Protect external metal against rust
Wipe a very light coat of AMSOIL FLP onto all exposed external metal — barrel, slide, receiver, controls — especially before storage in humid, coastal, or unconditioned environments. This is the corrosion-protection step that prevents rust on carry guns and safe-stored firearms.
6
Reassemble, function check & wipe down
Reassemble the firearm per the owner's manual and perform a function check (safety, trigger reset, slide / charging handle cycle). Wipe the exterior with a clean cloth so handling oils and excess lubricant don't transfer. The firearm is now cleaned, lubricated, and protected for carry, duty, or storage.

Firearm Platforms & Use Contexts

AMSOIL Synthetic Firearm Lubricant & Protectant is trusted across rifle, pistol, shotgun, and revolver platforms, in roles ranging from concealed carry to competitive shooting:

AR-15 & AR-10 Rifles

Bolt carrier group, charging handle, buffer, and rails. Reduces carbon adhesion through long range sessions and duty use.

AK-Platform Rifles

Bolt carrier, trunnion contact surfaces, gas piston. Holds film through dust, mud, and sustained fire.

Glock, Sig Sauer, 1911 Pistols

Slide rails, barrel hood and lugs, recoil spring. Light film performs better than over-oiling on polymer- and steel-frame pistols.

Bolt-Action Rifles & Shotguns

Bolt lugs, bolt body, action rails. Long-term rust protection between hunting seasons in humid storage.

Revolvers

Cylinder pin, hand, and crane. A thin film keeps the action smooth without contaminating ammunition.

Concealed Carry & Home Defense

All-metal corrosion protection against sweat and humidity on daily-carry firearms.

Competitive Shooting

USPSA, 3-Gun, IDPA — reduces friction on high-round-count slides and bolts for consistent cycling.

Hunting

Wet, cold, and humid field conditions — protects against surface rust on barrels and actions.

Military & Law Enforcement

Duty-grade lubricant performance from sub-zero patrol to sustained training fire.

The Complete Guide to AMSOIL Firearm Lubricant & Protectant

Why a synthetic firearm lubricant matters

A firearm's bolt carrier, slide, and rails see extreme conditions in a very small package — high pressures, hot combustion gases, abrasive carbon fouling, and rapid metal-on-metal cycling. AMSOIL Synthetic Firearm Lubricant & Protectant uses synthetic base stocks and additives engineered to cling to those wear surfaces, keep them sliding, and resist the carbon adhesion that gradually slows cycling and increases stoppages.

Carbon fouling reduction on AR-15 bolt carriers

On direct-impingement rifles like the AR-15 and AR-10, hot gas dumps carbon directly onto the bolt carrier group and bolt face. AMSOIL FLP forms a film that keeps that carbon from baking onto metal, so cleanings get easier and reliability holds through longer round counts. Apply a thin film to the BCG rails, cam pin, gas rings, and bolt lugs before each range session.

Corrosion protection for humid and coastal climates

Firearms stored or carried in Florida, the Gulf Coast, or any high-humidity environment fight surface rust constantly — even on stainless and nitrided finishes. A light wipe-down of AMSOIL Firearm Lubricant & Protectant on all exposed external metal blocks moisture and salt-air exposure, dramatically slowing rust formation on barrels, slides, receivers, and exposed controls.

Synthetic gun oil vs. traditional CLP

A traditional all-in-one CLP often compromises on lubrication. AMSOIL pairs Firearm Cleaner and Protectant (FCP) — which dissolves carbon and powder fouling and leaves a corrosion-resistant film — with Firearm Lubricant & Protectant (FLP), a dedicated synthetic that lays down a tough lubricating film. The result is better cleaning power plus a longer-lasting, more temperature-stable lubricant film than typical one-bottle CLPs.

Apply a film, not a flood

The most common mistake with any gun oil — synthetic or not — is applying too much. Excess oil attracts grit and sand, runs into magazines and ammunition, and burns off as smoke under sustained fire. A thin, even film on rails and wear surfaces consistently outperforms an over-oiled gun for both reliability and cleanliness.

Firearms Lubricants — Frequently Asked Questions

What is the best synthetic lubricant for firearms?▾

AMSOIL Synthetic Firearm Lubricant & Protectant (FLP) is widely regarded as one of the best synthetic gun oils for AR-15, AR-10, AK-platform rifles, Glock, Sig Sauer, 1911, bolt-action rifles, shotguns, and revolvers. It clings to metal, reduces carbon fouling, protects against rust in humid climates, and performs from sub-zero to high-heat range fire — without gumming or varnishing.

Does AMSOIL make gun oil?▾

Yes. AMSOIL produces a dedicated firearms line — Synthetic Firearm Lubricant & Protectant (FLP) and Firearm Cleaner and Protectant (FCP). Together they cover the lubricate, clean, and protect roles, with FLP as a purpose-built synthetic gun oil and FCP as an all-in-one cleaner that leaves a corrosion-resistant film behind.

What is the best cleaner and protectant for AR-15s?▾

Pair AMSOIL Firearm Cleaner and Protectant (FCP) with AMSOIL Synthetic Firearm Lubricant & Protectant (FLP). FCP dissolves carbon and powder fouling on the bolt carrier group, bore, and chamber while leaving an anti-corrosion film; FLP then coats the BCG, charging handle, buffer, and rails to reduce wear and resist carbon adhesion through long range sessions and duty use.

How do you lubricate a semi-automatic pistol?▾

After cleaning the slide, frame rails, and barrel, apply a thin film of AMSOIL Synthetic Firearm Lubricant & Protectant to the slide rails, barrel hood, locking lugs, barrel/bushing contact area, and the outside of the barrel where it touches the slide. Wipe excess off the exterior. A light, even film outperforms over-oiling, which attracts grit and burns off into smoke under sustained fire.

Is synthetic gun oil better than CLP?▾

Synthetic gun oil typically outperforms a one-bottle CLP on the lubricant and protectant side — better film strength, wider operating temperature, and longer rust protection. For maximum performance, use AMSOIL Firearm Cleaner and Protectant (FCP) to clean and protect, then AMSOIL Synthetic Firearm Lubricant & Protectant (FLP) to lubricate.

How often should you clean and oil a firearm?▾

Carry and duty firearms should be wiped down and re-oiled lightly every 1–2 weeks of carry, with a full clean after any range session or exposure to rain, sweat, or salt air. Range-only firearms can typically be cleaned every 250–500 rounds, or sooner if accuracy or function degrades. AR-15s and AKs in dusty or wet conditions benefit from more frequent BCG re-lubrication.

Will AMSOIL Firearm Lubricant gum up or attract dust?▾

No. AMSOIL Synthetic Firearm Lubricant & Protectant is engineered not to varnish, gum, or lacquer like petroleum-based gun oils can. Applied as a thin, even film — not flooded — it lubricates and protects without significantly attracting more dust or sand than other quality synthetic gun oils.

Is AMSOIL gun oil safe on polymer frames and Cerakote?▾

Yes. AMSOIL Firearm Lubricant & Protectant and Firearm Cleaner and Protectant are formulated to be safe on common firearm materials including steel, stainless, aluminum, polymer frames (Glock, M&P, Sig P-series), and modern coatings such as Cerakote, nitride, and parkerizing.
