I have been looking around at PTFE coated cylinders for my Bar-10, but I don't know if I can justify spending that on a component that doesn't significantly affect performance and only really gives a slightly easier bolt pull (my field limits to 400 fps on .25's so i'm just using the stock spring).

Is it possible (or reasonable I guess) to wrap the cylinder length-wise in teflon coated tape: McMaster-Carr

I think I would have to sand my cylinder guides to use this, but does anyone think there is anything extremely bad about doing this? I would get one wide, short strip (wide enough to wrap around the cylinder completely), cut out a hole in the bottom for the trigger mech and stick it on, making sure it is long enough to go all of the way to the cylinder head, and all of the way back to the bolt handle assembly.

The only major issue I can think of now is keeping it from peeling, but I think i'll be fine if I can get all of the grease off the outside of the cylinder, and maybe etch it with some sandpaper for a better stick.

Thanks!

Just use a high quality lubricant that contains Teflon on the outside of the cylinder. Break-free CLP is my recommendation. I have a rifle which uses no guide rings at all and the pull is very smooth.
The secret is a zero trigger and good lubricant.

If your field limit is 400fps then you do not need a Teflon cylinder as the bolt pull would be easy anyway. Just use a stock standard cylinder.

Everyone tends to just use Super Lube. It seems best containing PTFE I think from what I read which is (teflon of the sort).

I also keep seeing the WD-40 Dry Lube that has PTFE, but I don't know much about it. People usually stay away from WD-40 in general, but that is obviously for the penetrant kind.

Thanks for the advice, I will look into finding some good PTFE lube. If I really did need need the teflon cylinder though, would this idea be a viable one?

EDIT:

For 'Super Lube' Do you mean the oil or the grease? Also, could I use this to lubricate the piston/piston o rings?

Still have no idea. I mean you could try it out and tell us haha. Just tape. Worst thing that can happen is that it gets caught and clogged leaving you to have to remove it all.

As I have just been using silicon oil I think you should just try Super Lube oil. Super lube grease would be better for aegs, bearings, sears and what not, but you could also try to use the grease. Worst case scenario is that the grease picks up debris and what not like mine does with lithium grease (remember the bolt cover mod!). Don't take my word for it though..
