Would there be any disadvantage to applying one layer of teflon tape between the scope tube and rings? If applied carefully, across the entire interior surface of the rings, wouldn't it keep the scope from getting ring marks and provide some degree of extra grip once the rings are tightened?

Just for the heck of it I mounted my new scope tonight and did just that. I won't be shooting within the next week or so. I figured I would poll the forum and see if there was a theme of "dissenting opinions" within the replies.

My rifle is a 700 LTR in .223, the scope is a Bushnell Elite 4200 and the rings are Burris Xtremes.

the reason you don't did the same answers here, as on snipershide, is here no one believes 1) you are serious 2) you know what teflon is.

Let me first say Welcome to Optics Talk.
Now for your question. No I personally do not believe that it is wise or necessary if you are using quality materials to begin with. There are a few ring makers that the rings are of poor quality that such a practice might be beneficial. Thus the reason for using good stuff to start out with.

I've seen so called "quality" rings out of spec before, some more some less; YMMV.  Normally the ring is under sized just a hair as the cutter is getting old.  Therefore the tape just helps to pinch the scope.

That may be, But! If the so called "quality" rings are out of spec then ring marks are likely to occur anyway. teflon is subject to cut or crush and may not offer any help, but it isn't likely to cause any additional damage. I see what he's hoping for, but as mentioned lapping may be the better option.

if you don't want it to slip  and want to use a tape use double faced scotch tape or better yet skate board tape.

If you dont want any scratch marks on your scope use Burris Signature rings with the plastic inserts.

Teflon tape has a very low coefficient of friction; in other words it is slippery. Teflon tape is used as a lubricant and gasket between the threads of fittings. You don't want to use Teflon between scope rings any more than you would want to have oil between the rings and the scope. I often recommend wiping a thin layer of (red or blue) liquid thread locker (loctite) on the inside of the rings if you want to increase your ring holding strength.

If you want you avoid ring marks you might want to try Dale's suggestion of double sided tape.

When did tape become the way to avoid ring marks?

I was not suggesting double sided scotch tape as a preferred method of mounting. But I haven't seen similar material used in very cheap rings. It does seem to reduce ring marks in those cases. Personally, ring marks don't bother me at all. A light coat of decent spray paint does away with them, if a person really cares. That gives me an idea for a new thread...

Believe it or not, I use electrical black tape cut to fit the rings and have for years. No ring marks on scopes ever. You do have to clean up the sticky residue on the scope and rings if you remove the scope from the rings which I seldom do.

In addition, this eliminates the need to lap the rings.

The black tape is sticky in the ring side and rubbery on the scope side and helps lock the scope firmly in place in the rings. In fact, when I remove horizontal stye rings the scope has to be slightly popped out of the bottom rings. Works just as well with vertical style rings as well.

As for Teflon tape, as others have stated, I wouldn't use Teflon tape as it is very slick and I think you'd really have to crank down on the ring screws more than they are designed for.

Thin, clear, double stick tape might work too, I never thought of that. But of course the thick foam types of double stick tape wouldn't work due to the thinkness.
