Suppressor Maintenance



Both the Reflex and Z-Jet suppressors are practically maintenance free devices. However any suppressor should be cleaned after a shooting session to prevent corrosion to both the suppressor and the host weapon from nitric acid containing combustion products.

Remove the suppressor or leave the action of the rifle open after use to avoid corrosion by letting condensation evaporate away. A small amount of light gun oil sprayed into the suppressor will help prevent corrosion. Roll the suppressor around to spread the oil over all interior surfaces.

Normal fouling from powder and primers does not effect the suppressor's functioning. Loose solid impurities like powder grains and carbon chips are easily removed by shaking the suppressor, while keeping it vertical, front end down. Washing with liquids or solvents is unadvisable.

Store weapons muzzle down with the action open to promote air circulation and prevent oil and fouling from entering the action.

Oils & Coolants

We performed three tests on the various oils and coolants listed below to determine their suitability as preservative oil or suppressor coolant. Results are in the right hand column below.

Test 1: Spray on metal surface and allow to dry for 6 days.

Test 2: Heat 6 day test surface with propane torch and observe smoke production.

Test 3: Test fresh product on red hot heating element and observe smoke production.


Rig #2 - Oil

This oil is excellent for use in suppressors because it is thin and spreads easily throughout the interior of the suppressor. Does not produce an excessive smoke signature.

1. Slight drying but still liquid. Not tacky or sticky.

2. No smoke

3. Small amount of white smoke.


Militec-1 Oil

This high tech oil isn't a cleaner but it will ensure a suppressor doesn't rust or corrode after use. It is the prefered oil for use on infantry weapons due to its dry lubrication and rust inhibiting properties. Oils that remain wet or tacky can attract dust and grit to weapons. Militec-1 is light enough to be easily distributed throughout the interior by rolling the suppressor after spraying the oil inside.

After testing we cannot recommend the use of this product inside a suppressor due to the generation of large amounts of white smoke during firing.

1. No change.

2. Slight smoke

3. Medium to large amount of white smoke.


Break Free

One of the oldest firearms lubricants, still makes for a reasonable coolant medium. Break Free is a bit thick to be used solely as a preservative oil, making it difficult to spread throughout the interior of a sealed suppressor. Thinner oils are a better choice as a preservative.

1. No change.

2. Slight smoke

3. Medium amount of white smoke. May catch fire and produce black smoke.


CCF Suppressor Coolant

Specifically designed as a coolant medium for modern suppressors. CCF Suppressor Coolant is unaffected by heat or pressure, has a "clinging" quality that resists migration out of the can so it can last 70 - 100 shots before recharging is required. This coolant does not burn to create a smoke signature. CCF Coolant won't dry out over time and even acts as a corrosion inhibitor. Available in pistol and rifle grades.

The above comes from CCF advertising. We did find that it would burn at high temperature.

1. No change. Spreads over the surface very well.

2. Slight smoke.

3. Small amount of white smoke. May catch fire and burn. Leave white ash.


MPro-7 Gun Cleaner

This non-toxic cleaner is a combination of chelating agents, corrosion inhibitors and surfactants designed to clean carbon oil and grease off metal surfaces. Thinner than most common gun oils, it is relatively easy to spread throughout the interior of a suppressor by spraying and rolling. Non-flammable MPro-7 won't create a significant smoke signature. Use as a coolant only.

1. Dry and tacky.

2. No smoke.

3. Very lite smoke production. Could be vapour.


MPro-7 Gun Oil

Low viscosity, non-flammable, non-toxic oil. Non-flammable means it won't produce a smoke signature. Use for preservation or as a coolant.


Mobil PremiumLubrication Grease

The lithium content of this grease gives it a particularily high latent heat of evaporation making it ideal for use as a suppressor coolant medium. Lithium grease has a melting point of 230C (450F). Grease coolant will not leak out of a suppressor or dry out over time, allowing a suppressor to be charged with coolant well before it is needed. Thick and non-sprayable it may not be easy to get into a sealed suppressor.

Shooter's Choice All Weather High-Tech Grease

Used by some operators as a suppressor coolant medium because it is packaged in a small plastic syringe making it easy to recharge the suppressor. This grease has a melting point above 177C (350F). Grease coolant will not leak out of a suppressor or dry out over time, allowing a suppressor to be charged with coolant well before it is needed. Only drawback is cost.

Silencer History and Performance Vol II

1. No change

2. Lite smoke, smells waxy.

3. Lite smoke, smells waxy.



DO NOT use WD-40 for cleaning or maintaining suppressors. WD-40 becomes gummy as it dries out and it creates a prodigious amount of white smoke when it burns.


Field Expedient Suppressor Coolants

Do a bit of reading on the subject of suppressor coolants and you will find shooters using all sorts of every day materials as suppressor coolants. some of these can work quite well and some are not a good idea at all. here are some of the more common ones and a few that may not be so common at all.

Shaving Cream: A faily popular choice with no obvious major drawbacks. May be popular with 007 types for the chic smell factor. Make sure you clean the suppressor and weapon thoroughly after using this stuff.

Soda Pop: Not a good idea at all! Pop is very acidic and will cause corrosion inside the suppressor and weapon over time. Regular soda contains a lot of sugar that will burn and carbonize into a thick sticky mess that is exceedingly difficult to clean up. Some shooters choose diet sodas but a number of diet sweeteners are sugar based and will cause the same problems as regular soda.

Urine: OK, seriously smelly and disgusting but Al Paulson found it was one of the most effective coolants available and it is easy to get, especially in the middle of a serious firefight. Comes in a handy and easy to use dispenser which almost seems made for charging suppressors however you will have to endure some stares from your fellow soldiers when recharging your suppressor. Offer to fill their suppressor too and I bet they go away. :)

Water: Simple and easy to use. Available just about anywhere. Just dip the suppressor in, let it drain and the weapon is ready to shoot. May not last as many shots as other coolants but it is second only to urine in the easy to find department.

Saline Solution: Slightly salty water. Should work about as well as urine but without the stink and social stigma. Medics have lots of this stuff and armies have lots of medics. However, may be in short supply in the middle of a battle. Grab a bag before you leave base.

Ultrasound Gel: Water based, this product won't burn or cause a bad smell. It lasts longer than water and is cheaper than many other coolants. It also won't get you funny looks at the pharmacy. Buy it by the gallon online

K-Y Jelly: Similar to ultrasound gel but may be a bit embarassing to buy in quantity. Although if the cashier is cute there could be a secondary benefit.

ATF (Automatic Transmission Fluid): Only use this stuff if you don't have anything else and you don't mind a stink.
