In any sport, everyone is
looking for better technology to help them be better, faster, more
accurate. One of these technologies is
the use of carbon fiber. It is a lightweight
material, as strong and often times stronger than steel. It has been used for years in the automotive
and aerospace industries. Its major
drawback is cost.
Carbon fiber technology is also
available to the shooting sports. One
form is in carbon fiber wrapped barrels.
I was curious about this technology so I purchased a couple of these
barrels to find out for myself if carbon fiber wrapped barrels are worth the
money.
The barrels I chose were
manufactured by Proof Research, a leader in carbon fiber technology. (Proof Research)
The first barrel is a 16
inch barrel for an AR15 chambered in 223 Wylde.
It is of medium weight configuration. The barrel Starts at one inch diameter at the chamber, tapering down to .75 inches
at the muzzle. This barrel was assembled
into an AR15 by myself.

The second barrel is a 20
inch heavy target barrel chambered in 6.5 Creedmoor. It is 1.2 inches at the chamber and necks
down to .875 inches at the gas block.
This barrel came assembled
into a complete rifle manufactured by NEMO arms. (NEMO Arms)

Let’s look at the advantages
and disadvantages of carbon fiber barrels.
Weight:
The big advantage of carbon
fiber is saving weight. Proof
Research claims up to a 60% savings in weight.
The amount of weight savings depends on the diameter and length of the
barrel.
The 16 inch barrel I chose
is 26 ounces. As compared to 33 ounces
for an equivalent steel barrel. This is
a 22% savings in weight.
The 20 inch 6.5 Creedmoor
barrel is 3 pounds. The equivalent steel
would be 2-3 pounds heavier. Up to a
50% weight savings. Now you are talking
some serious weight savings.
Accuracy:
I found the carbon
fiber wrapped barrels to be just as accurate as steel barrels.
Typical accuracy is 1 inch
and better. With the heavy target barrel
giving me a consistent .6 inches. (No pictures available of heavy target barrel accuracy)
First 3 shots - cold bore.
(Australian Outback, 69 grain SMK)
Next 3 shots - New ammunition
Last 10 shots of shooting session. Approx. 20 shots between first shots and these last shots.
(Yep getting a bit tired and I forgot my rear bag. So not as stable as I wanted to be)
(Yes, I'm making excuses for my poor shots.)
Cost:
This is the category carbon
fiber barrels lose. They are 2-3 times
the cost of a steel barrel.
Most run approximately $900
- $1000. Most steel barrels are $250 -
$500.
Conclusion:
Are carbon fiber barrels
worth the money? No and Yes. Your end use and configuration of your rifle
will determine if a carbon fiber barrel is worth the money.
In the lighter weight 16
inch barrel, I would say no. It is not
worth the money. The carbon fiber barrel
is three times the cost ($1000 vs. $300) and only saves 7 ounces. Hit the gym and get
stronger is a better solution.
In a longer, heavy barrel
configuration I would say yes. Carbon
fiber barrels are worth the money.
Especially if your end use is a run and gun type competition or hunting
the back country and high degree of precision and accuracy are needed minus the
weight.
On the 20 inch NEMO AR10 I
purchased, I am saving 2-3 pounds of weight.
I have the benefits of a heavy target barrel without the weight
penalty. Yes, worth the money. Overall I have a 10 pound rifle versus a
12-13 pound rifle.
