Home Forums Hunting & Shooting Handguns Favorite semi-auto lube ???

The majority of commercial gun oils are simply rebranded transmission and motor oils.


Due to being in charge of U.S. Embassy armories at numerous locations oversees, I have maintained literally thousands of weapons.

Cargo/Connex boxes full of the things.





Belt fed MGs, bolt action sniper rifles, handguns, you name it.




What do I use:

Motor oil.



0-W20 in the winter, and a heavier oil for the summer.

I have a BUNCH of samples I have used from visiting various defense manufacturers, and industry reps and none of them do anything any better than plain old motor oil.
