Used and recommended by major firearms manufacturers, Lucas Extreme Duty Gun Oil is specially formulated for high volume, high heat and friction firearms and was designed for full auto firearms, SBRs and suppressors as well as semi-auto rifles, shotguns and pistols. It offers superior burn-off, shock and heat resistance, unlike any other multi-purpose gun oil. A unique additive keeps the oil from running and migrating while the polymeric film protects from rust, wear and moisture and resists carbon, lead and copper fouling and dramatically reduces wear during all shooting conditions. Applying Lucas Extreme Duty Gun Oil to bores, bolt carriers and gas pistons makes clean-up of powder residue, copper and carbon fouling a much easier task. Apply a light coat to suppressor baffles, mounts, muzzle breaks and flash hiders to resist carbon build up and to make cleaning quicker and easier. It neutralizes acids from fingerprints and resists drying for long term storage use.

  • Developed for demanding lubrication during hard use.
  • Extreme working temperature range of -38°F to 400°F.
  • Great for ultra-sonic cleaner use for small or bulk parts lubrication.
  • Superior blow back resistance, keeping oil out of your face and off your glasses.

Review Summary
The EXTREME DUTY GUN OIL receives high praise for its exceptional viscosity and durability, making it suitable for various firearms. Users appreciate its long-lasting lubrication and resistance to environmental challenges, with some mentioning a chemical smell. However, a few reviews highlight issues with packaging, particularly regarding the cap's design, leading to leaks. Overall, it's considered a top choice for gun maintenance.

Long Lasting Film
I'm just a sportsman shooter and one thing I can say about Lucas Oil Extreme Duty is that it has a long lasting film and that's important when you do shoot between hundreds or thousands a round per day and to me that's important.I also like to 1oz bottle because you can apply the lube in hard to reach places thanks to the needle on the bottle.My next test will be to see if this product reduces barrel temperatures.Finally there is a gun oil on the market that can withstand Heat!

Excellent gun oil
The only lubricant you will ever need.It's heavier viscosity, about 20w or 30w.Good for any firearms, collectors to EDC to recreation.I have found there is a bit of a smell, mostly 'chemical' smell to it.If you don't mind that, it's great.Does not burn off, smoke, or sling off when being used.Also does not dry up or turn 'gummy' after storage.A bit pricey, but an 8oz bottle will last a while.This is the best gun oil I have found over other brands.Hope that info helps.

Bottle is difficule to squeeze, but ....
I like Lucas gun oil for the reasons mentioned in previous reviews, and the needle applicator is a definite benefit for certain applications such as narrow pistol slide rails.The factory bottle I have, however, is very difficult for my old fingers to squeeze to dispense the oil.I placed the needle cap on a bottle that isnt so stout and now I love it.

It is not required, but for this product to penetrate into the steel it will need to be clean.
