A factory Remington 700 requires a barrel custom-machined to fit your specific action, as it's not possible to create a universal shouldered pre-fit barrel for the factory actions. That's where our barrel blanks come in! Our barrel blanks have been drilled, rifled, contoured, and passed through our quality control stations; the remaining processes—chambering, threading, crowning, and fitting to your action—will be completed by a gunsmith.

Unfortunately we do not offer custom 1:1 barrels. Our website reflects all of our current available configurations.

Our pre-fit barrels are available in most standard calibers, lengths, and twist rates. For greater customization, consider our bolt-action barrel blanks. These blanks provide unmatched versatility with endless chambering options, along with a wider selection of lengths and twist rates.

All Intermediate, Rifle +1, Rifle +2, and Rifle +3 gas length barrels do include the proper gas tube. Our barrels do not include a gas block.

If the product you’re looking for isn’t in stock with one of our dealers or distributors, we recommend contacting a dealer directly. They can assist with placing an order for you or provide an update on when they expect to restock.

When it comes to cleaning, we recommend a “less is more” approach. If the barrel is performing well, there’s no need to clean it after every use-simply store it away safely. Over-cleaning can sometimes lead to chasing accuracy, so it’s best to clean only when you notice a drop in accuracy, have been in harsher elements, or after a few hundred rounds. For cleaning, we suggest using a non-ammonia-based product like Boretech Eliminator or a similar cleaner. In most cases, wet and dry patches will suffice, but if a deeper clean is necessary, a nylon brush can be used.

Our AR-15 barrels are designed for standard M4 extensions. Our AR-10 barrels are compatible with DPMS Gen-1 extensions. Our 6 ARC barrels utilize a 6.5 Grendel Type II bolt. It is recommended to contact your rifle/component manufacturer to determine what they utilize on their platform.

The honest truth is that very little is needed for barrel break-in. Our meticulous lapping process during manufacturing ensure the barrel is essentially ready to perform right out the box. While we include a general shoot-and-clean break-in procedure in our manual, it’s more of a guideline than a requirement. While following a break-in process won’t hurt, it’s not necessary.

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. Barrels are available for ARs in a variety of different calibers, lengths, twists, and gas system lengths. We offer many options for bolt-actions that include our barrel blanks and pre-fit barrels for select actions/platforms.

We have three basic contours for bolt-action barrels—Sendero, Sendero Light, and a Bull. 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. You can also contact us via email or phone and chat with a member of our team for recomendation. 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.

All our products can be purchased through any PROOF authorized dealer. Please check out the dealer page of our website. From here you can browse all of our online dealers or locate a dealer nearest you.

We do not recommend Cerakoting over the carbon fiber portion of the barrel. However, you can certainly Cerakote the steel portion of the barrel using an H-Series Cerakote. Please refer to the Cerakote website for instructions and recommended baking temperatures.
