Our carbon fiber barrels are 10 times stronger than steel by weight and nearly impervious to weather, nicks, dings or scratches.
Generally speaking, our bolt-action carbon fiber barrels will weigh 3 to 3 ½ pounds. Carbon fiber AR barrels will weigh between 1 ½ to 2 ½ pounds depending on length and journal size. Check the product page tech specs for exact weights.
Not entirely. At the heart of each barrel is a stainless steel “barrel blank” that has been contoured to our specifications prior to being wrapped in carbon fiber. Areas to be threaded, such as the breech, muzzle and gas block journal (where applicable) remain steel.
No. All of our PROOF Research carbon fiber-wrapped barrels are brand new blanks that we contour to our specifications and wrap right here in Columbia Falls, MT.
We do. Carbon fiber-wrapped barrels are available for ARs in most common lengths, twists and gas system lengths with journal sizes of .750 and .875. View a complete list of PROOF Research AR barrel specs at www.proofresearch.com/barrel-specs. Bolt-action barrels are available in most common calibers, twists and lengths.
We have three basic contours for bolt-action barrels—Sendero, Sendero Light and a Sendero for .338 calibers and larger. The standard Sendero is available with a shank diameter of 1.200” (or 1.250” for .338 and larger) and measures .900 at the muzzle on a 28” barrel. The Sendero Light measures .800” at the muzzle on a 26” barrel. We also make a bull barrel which measures 1.200″ down the length of the barrel.
Most bullet manufacturers have informative websites regarding the best twist rates for specific bullets, however, please feel free to inquire of our sales staff. We’re happy to offer advice to assure you’re getting a twist rate that’s appropriate for the bullets you intend to shoot.
Your bolt-action barrel will arrive ready for thread and chamber by your gunsmith. Your AR/Pre-Fit barrel will arrive threaded and chambered.

We do not recommend Cerakoting over the carbon fiber portion of the barrel. However, you can certainly Cerakote the steel portion of the barrel. Below is our recommended application process:
1.) Clean the action in a solvent tank to remove wax and oil (carbon fiber does not go in the solvent.) We recommend using Crystal Clear/Brakleen degreaser (nothing aggressive.)
2.) Tape the carbon with Cerakote recommended blue high temp vinyl tape.
3.) Blast action and barrel that is getting a cerakote finish - blast cabinet set at 100 PSI with 100 grit aluminum oxide media.
4.) Blow everything off with 100 PSI air to remove all media dust from the parts.
5.) Retape carbon with Same blue vinyl tape from Cerakote.
6.) Cerakote all necessary surfaces and flash cure-no heat for 15 min.
7.) Place all parts in oven at temps between 150*-180* for 15 min. then remove from oven.
8.) Remove all tape and return to same temp oven for 2 hours to fully cure.
