Gun oil and teflon (ptfe) ?

[Welding Rod]

Has any negative side effect ever been actually observed in a gun barrel? Or is a corrosive side effect based on theory?

Like I said, I have been using Tetra w/PTFE for 10-12 years in about as wet an area you are going to find in the lower states and have never seen any corrosion.

I have been using it in ARs for years now and the reason I have stuck with it is because the bolt and inside the bolt carrier are so easy to clean.

Since the gun oils in questions have less than 1% teflon , is that even enogh to do anything good or bad ?

I dunno.... I've been using tri-flow made with PTFE....never had a problem and all my guns run great......

i don't believe the whole industry and consumers will buy the empty ad just to feel good about themselves, there got to be proven merits of teflon

Again, look at all the car owners who do exactly that. Or the gun owners who use graphite lube in the aluminum receivers of AR's, even though graphite is mildly corrosive to aluminum.

Since the gun oils in questions have less than 1% teflon , is that even enogh to do anything good or bad ?

Burning 1% Teflon will probably net you about a quarter of a percent of fluorinated acids. That's not a whole lot.

A tiny bit of water with a quarter-percent salt might not do noticeable harm either, unless you leave the gun uncleaned for years in a humid environment afterward.

However, neither is something I'd necessarily *want* in the bore if there are other products that don't leave even trace amounts of corrosives.

Has any negative side effect ever been actually observed in a gun barrel? Or is a corrosive side effect based on theory?

Theoretical, mostly. If you clean the bore after shooting, it would be like shooting mildly corrosive ammo and cleaning it afterwards. You'd probably have to leave the bore uncleaned after shooting for a long time in a humid environment to see corrosion, and a lot of AR bores are chrome lined also.

So when are we going to see Hornady release their Ultraperformance ammo, loaded with a drop of Cheetah blood?

I'm sure someone at some time thought Teflon was a good idea beyond marketing.

Lucas Gun Oil, cheap and it works on machine guns and sewing machines.

Run,... from any product with the name Lucas on it.

Just my .02 cents worth.

Well, it doesn't involve electricity, so the Lucas product might be ok.

OTOH, do you know hwy the Brits drink warm beer?

Lucas made refrigerators too.

Back to the parent topic. I did run across this:

Firearms cleaner, lubricant or preservative oil or grease containing PTFE additive applied
to sliding surfaces of the M14 rifle will not reach a temperature of 464 degrees Fahrenheit
or higher with the possible exception of the cylindrical portion of the operating rod and the
operating rod guide. Thus, firearms cleaner, lubricant or preservative with PTFE additive
will remain chemically inert when applied to the saddle portion of the operating rod and
areas to the rear. Application of any cleaner, lubricant or preservative oil or grease
containing PTFE additive forward of the chamber may result in deterioration of the PTFE
additive.

Experience of the U. S. Marine Corps found that when CLP containing PTFE additive was
left in the bore of a M14 rifle it would shoot erratically until the CLP had been blown out
after the first fifteen to twenty rounds of fire. The accuracy would return indicating the
washing out of the CLP with its PTFE additive. Even with automatic fire, it’s unlikely any
portion of the barrel surface would reach 464 degrees Fahrenheit or higher in no more
than twenty rounds. If the M14 rifle was fitted with a sound suppressor, the propellant
gases and any residual bore cleaner or preservative will blow back into the shooter’s face
each time the rifle is fired. If the bore cleaner or preservative contained PTFE additive
then it is conceivable that some PTFE high temperature particulate or off-gas could be
blown on to the shooter.

I'd share the whole book but it's copyrighted.

Lotsa repetition. More than is needed...
