Anyone have any experience with carbon fiber barrels?

Are they worth it for the loss of weight and heat? Do they last as long as modern steel barrels?

    There is no good reason for a carbon fiber barrel.

      I can see it have a place in super gucci hunting circles. It's not like you'll be shooting much, and the lower weight is probably worth it.

      That and gear queer .22LRs.

    I had one of these of proof research. Its lighter, but you could also get a lighter profile and have the same effect. Given these are for precision you are for more likely to shoot out the barrel instead of having the carbon fiber degrade. Its really not worth it unless you like the aesthetics so much you are willing to shell out the funds. Proof Research have very accurate barrels though.

    Fibers generally behave badly when subject to stress at high temperatures; the friction between them and the glue will heat them and they lose cohesion.
    Barrels are made of steel, usually martensitic simply because of the need to withstand high pressures.

      >usually martensitic
      You sure about that? Seems like it'd be rather easy to accidentally temper away, especially on semi-autos. And it isn't like you can't make it stand up to the pressure regardless, all it takes is a touch more material.

        martenstic inox have high chromium quantities, Bain's curve are moved to the right by a lot, they are in fact called auto-tempering steels because they are cooled by air after leaving the oven

          Martensitic has to do with the crystalline structure of the steel not the chromium content.

            The various A, B and M in the graph he posted are different crystalline structure (M for Martensite), and various alloying elements will shift those zones around.

          That'll only help if we push the heat up past the A3 (or at leats A1) line whenever things get hot enough to have an effect on the martensite which I think may be a bit extreme (at least for something that we're relying on to be a common occurrence). I'm thinking more of plain old overtempering. And, frankly, if we do shoot up around A3 temps then the idea of making the barrel martensitic to stand up to the pressure is obvious nonsense anyway, since the barrel can apparently stand up to the pressure well enough even when it's heat-weakened and unhardened.

    I've seen horror stories on /n/ of carbon fiber bikes breaking with no warning because they don't handle long term stress very well.

    If you apply that to a gun barrel, it seems like there are going to be a lot of really dangerous KBs.

      People who buy cf bikes probably ride them daily. People who buy cf rifles probably fire about 6 rounds a year.

      The early ones, definitely. It was pretty groundbreaking stuff, massive weight savings in a sport where things are measured in grams. I have a lot more faith in carbon frames now that they’re no longer in beta, but you have to baby them. I’ll stick with my aluminum.

      carbon fiber barrels are really carbon fiber sleeves over a thin steel barrel. a pure carbon fiber barrel would be a disaster.

      CF mtb frames have always been pretty good. It's mostly the road bikes that got problems because the frame has no suspension and cf doesn't like impacts...
      Ive heard of people crashing mtb and the frame hit a rock and cracked it.

    I haven’t personally owned one but pure carbon is the best possible conductor of heat and extremely tolerant of high temperatures, which is why they are trying to move computer chips to pure carbon instead of silicon. The carbon fiber wrap is supposed to reduce weight and channel heat out of the barrel.

    wouldn't a carbon fiber lower or buttstock make more sense?
    surely there's more weight to be saved in a grip or an accessory rather than the fucking barrel

    They're awsome and worth it for hunting rifles. You get the advantages of a thick profile barrel and the weight advantage of a thin profile barrel. The only downside is cost. If you're building a 7mm mag or similar mountain hunting rifle with a long barrel it's completely justifiable. For any other application.... Probably not.
