Carbon rifle barrels

Jack, or someone who knows about these barrels made by Christianson Arms. I was wondering if any one has info on the carbon barrels for rifles like the .20 caliber. How is the barrel on copper or powder fouling?
Is the recoil a little higher than with my heavy steel barrel?
What is the price difference between the steel and carbon.
Are the riflings made the same way?
Can it be bought blank so I can send it out to have it done in Tactical.20?
Thanks,T.20
 
The last that I've read was that they are steel tubes with carbon fiber wrapped around that. The inside of the barrel is the same.Seems to be a good way to shave some weight. Was it Browning that advertise carbon barrels on their rifles at one time? Only to drop the idea in a hurry?
 
FALFire,
Glad to hear someone is working on it. It should be possible to make a lighter barrel accurate with carbon fiber. It sure seems to be working well with homebuilt aircraft.

i wouldnt recomend christianson arms barrels or rifles to anyone. i know of 3 that individuals around here bought and were sent back for various problems.
 
You guys are scaring me...I've got a .257 Weatherby Christensen Arms being made for me right now...They are a great looking, great feeling rifle...Hopefully it will shoot!
 
We use the volquartsen carbon fibre .22 barrels on our shop customs, and with the exception of the vq snake barrel, they are probarbly the most accurate rimfire barrel on the market, we love them.
 
I am having ABS make me a custom Carbon Fiber AR barrel as we speak, Starts out as a Mike Rock 5R 1-8 twist barrel blank (according to some, Rock barrels are some of the best match grade stainless barrels on the Market) and they do the rest! These barrels are from what I can tell the best thing going for the AR-15 (or any rifle for that matter) They give you the benefit of an H-Bar( shooting rapidly without having to worry about your barrel heating up and degrading accuracy) with the weight of a Pencil weight profile barrel. These things have been tested to the extreme under full-auto fire and still shoot as accurately as when they were cool. They are expensive, but will last twice as long or longer than what a regular match grade stainless barrel will give you.

Congrats, you will have one fine shooter no doubt. Mike Rock is the man. /ubbthreads/images/graemlins/grinning-smiley-003.gif

Since the barrel starts life as a regular barrel, there is absolutely no way for this to be a true statement. rapid cooling may extend barrel life (but I'd want to see proof) but to double barrel life? I call BS
 
they were quality control problems. fit and finish. 1 of them the bolt would hit the top of the comb when you pulled it back. i really cant remember the details. it was about 4 yrs ago the rifles were ordered from a banquet and returned for deficiencies.
 
I have to think that if anything, barrel life will be less with the fiber wrapped barrels. Carbon fiber does not conduct heat very well. This may keep the external surface of the barrel cool but only increases the temperature of the bore.
It is the bore temperature that determines barrel life.

This is straight from the ABS website on heating and accuracy.

Heat Management

We recognize that heat management is a critical element of building a better barrel. Carbon composite barrels built with ordinary fiber grades have a reputation of insulating heat. We use a patented method of applying a remarkable thermally conductive matrix that conducts heat 372% faster than steel. This technology has made our barrels thrive in the high volume world of gas operated semi and full auto firearms.

Accuracy

Many old technology composite barrels rely on tensioning a composite sleeve over a tiny barrel liner. There are flaws in this approach. When steel is heated, it expands; carbon shrinks when heated. Any heat changes the amount of tension in the barrel and as a result the harmonics change too. Our patented method of tuning the barrels by manipulating the helix angle of the fiber placement isn't heat sensitive. We offer benchrest accuracy with sporter weight.
 
Mine will shoot the factory 180 corlok in 3/8 group @100 yards. It has some freebore. I get about 100 fps faster than Rem. list.
