carbon wrapped barrels?

Does anyone wrap rifle barrels with carbon fiber? Reason I ask is I'm look at buying a short barreled rifle soon(ruger frontier) and heard alot about the short barrels, so I've been doing some research. I've found that while it can reduce your velocity (only by about 5% for the frontier) it can improve accuracy because shorter barrels have less vibrations and are stiffer. So that why varmint barrel are thicker is to make them sitiffer. So I was thinking why not just wrap the barrel with carbon fiber to stiffen it up?

There are companies that make carbon fiber barrels.
It is a thin wall barrel stiffened with a carbon fiber wrap.
They say accuracy is excellent, and the biggest advantage was it didn't heat up like steel barrels.

I have only seen them in magazines and often wondered how they would hold up. I have always wanted to try to wear one out, but not out of my wallet.

I believe Magnum research made a carbon fiber wrapped 10/22 barrel, and Remington made a rifle with a carbon fiber barrel. the Etronix IIRC, but its been out of production along time. And used propriatary ammo.

Magnum research and volquartsen both make carbon wrapped barrel for the 10/22 and they are excellent shooters

The remington one you mention was made by christiansen arms and they still make them. They are called carbon one.

The main advantage is they are very stiff without the added weight from a heavy target barrel. This can be a downside in larger calibers as the lighter a gun is the more recoil it has.

I have a whistlepig barrel on my 10/17 ruger and it is a very thin steel barrel with a thick aluminum sleeve bonded to it which makes it stiff but light.

Stay away from the butler creek and other cheap fiber wrapped barrels as they are junk.

that Etronix was an okay gun at best. i sold mine, wishing I had kept it now. It still had a steel barrel. I had #000429. it was a reps gun. Apparently not supposed to sell it.........

Well I'm looking at .243 so recoils not an issue. The aluminum isn't a bad idea but aluminum isn't all that stiff. I wonder if a how a home-made unit would fair. You can buy crabon tube and then just expoy it to the barrel.

IIRC, all the ones I have seen had a steel "disc" at the actiona nd crowns. Not sure the carbon wrap would stand up to the repeated heat from the escaping gasses at the crown.

Some of the carbon wrapped barrels have a fair amount of tension on the steel liner. I think it would be hard to do yourself.

Carbon should hold up to the heat, although you could cut it back a bit from the end of the barrel. Guess I'd be more worried about the expoy then the carbon.

Tension, having a hard imagining how you would get this. Compression maybe?

I think the disc you see on the muzzle of them is threaded onto the barrel liner. As it is tightened, it presses against the carbon outer wrap and pull tension on the barrel.

duh, I get it, just like a nut and bolt. So you could use a threaded barrel and screw on a carbon tube with a threaded insert expoyed into it. You would also need something on the rear off the barrel to seat the carbon tube.

IIRC The one I read about was 223, and I think it was in Varmit Hunter Magazine.
