I have been reading that teflon based oils such as Rem-oil are not recommended as the finishing oil before dry patching in a rifle barrel after cleaning. Anyone know why that is not recommended? Does the teflon adversly affect the performance? does it react with the copper solvent?

Teflon can prevent solvents from coming in contact with fouling. The solvent kind of sits on top of the teflon. Like water beading up on car wax.
As an interesting aside, at one time a product called Friction Block was popular. It really made a rough bore shoot better. But it was so insulative that it would prevent an electronic bore cleaner from working - it would not let the electric current pass through it!
Great stuff if you didn't want *any* chemical reactions.

Thank you for clearing that up. I would imagine that a brush would take the teflon out right?

I believe that Teflon produces real toxic fumes when submitted to high heat, like in a rifle bore.

Doesn't Breakfree CLP have Teflon in it? I have never heard anyone say not to use CLP in the bore.

Teflon is great for moving parts and places easily accessed for cleaning, but not something you want in the bore, it has tendency to find it's way into places you don't want it, building up and eventually filling and clogging. Since it is chemically inert, like solvents or even acids won't harm it it is a real "BITCH" to remove!

Marsh Mule,...Any ideas on getting it out if you come across a barrel that was treated for extended periods with a teflon oil?

The reason that I heard was from an accuracy point of view. You would get inconsistent results from a clean bbl. This is not good for target shooters with limited sighters or professionals who want to be sure of a first shot.

How many shots before the barrel becomes teflon free? I can't see it lasting forever, .....this is getting into some good info

There are millions of M16's that get nothing but CLP in the bore.

Just C;
best advice I can offer you is use a good bore cleaner, solvent and scrub hell out of it, not use that oil any more on the bore.
As far as all the M16's, the only MOA-accuracy they are worried about is MAN-OF-Angle, it is more like SPRAY-AND PRAY!
If and when Uncle Sams weapons accuracy degrades it gets a new Barrel, not a luxury everyone can afford.

Shooters Choice do the job?

Shooter Choice should work just fine!

Thanks,...I'll be scrubbing this weekend.

JustC,
I wouldn't worry too much about it. I would just refrain from using it. I think it will eventually shoot out. I don't know, because after I used Friction Block on my rifle the mag spring broke and I haven't shot it since.
If you have a Foul-out, clean it this weekend for us and let us know if you restored electrical conductivity. That's the best way to tell if it's really gone.

BECoole, don't have a foul out system, but have been considering one.

Didn't I read a thread a while back on making one at home?
