All Centerfire Barrels

"PROOF has cracked the code with high-performance carbon-fiber barrels.” - Outdoor Life Magazine

About half the weight of comparably-sized steel barrels. (Finished weight under 3 lbs.)

PROOF Research is proving carbon fiber-wrapped barrels aren’t just a lightweight alternative to traditional steel barrels, but that they provide superior performance, including extreme accuracy, unprecedented durability and increased barrel life. By combining our unique manufacturing process with advanced technology composite materials and thermo-mechanical design principles, we’ve accomplished what others have failed to do in the past—match-grade carbon fiber barrels that weigh a fraction of traditional steel barrels while compromising nothing. They’re not just lighter—they’re better.

NOTE: The Proof Research Carbon Fiber "Sendero" actually measures very close to the standard M24 taper. The Sendero Light is similar in counter to the Rem 700 "Varmint / Sendero" taper barrels.

PROOF Research pre-fit carbon & steel barrels for Zermatt Arms Origin actions make it easy to upgrade your rifle or change calibers. Our pre-fit Zermatt Arms shouldered barrels are easy to install. Simply thread it on, torque it down, double check headspace and head for the range.

Carbon fiber has long been hailed across many industries—aerospace, cycling, alternative energy—as a wonder material making everything lighter and stronger. When employed in a rifle barrel the benefits extend beyond reducing weight and increasing strength. Our patented manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks that are made in our firearms division. These blanks are then turned down to a significantly reduced profile greatly reducing weight. This reduced contour barrel is then wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin developed by our advanced composites division, PROOF Research ACD. The carbon fibers we use have a unique ability to diffuse heat along the length of the barrel (much like fiber optics transmit light). Carbon fiber also moves heat very effectively through the wall (thickness) of the barrel greatly increasing heat transport resulting in barrels that cool faster, maintain accuracy over longer sessions of fire, and live longer. The end result is an aerospace-grade, high-fiber content composite barrel that is stronger, lighter, as accurate as the finest precision steel barrel, and durable to perform in the most demanding environments. They’re not just lighter—they’re better.

PROOF Research pre-fit carbon fiber & steel barrels for the Impact Precision 737 are to be installed in a simple operation requiring few specialized tools. These barrels come chambered and threaded for an easy install - torque on, ensure headspace with proper gauges and head to the range!

As the leading supplier and producer in the world of Ballistic Test barrels as well as the very accurate Pro Series of hunting, target and tactical rifles, H-S Precision knows what it takes to produce a quality barrel. All barrel blanks are 416R Stainless Steel and feature proprietary 6-groove 10-X cut rifling process. Blanks are offered in multiple contours, from a lightweight sporter configuration to a large straight taper, and everything in between. Any common twist rate is available in any contour. They are available in both fluted or non-fluted configurations.

Choose from a lightweight hunting profile all the way up to a heavy tactical profile. These barrels are blanks and will need to be threaded, crowned, and chambered to your specifications. See the full description below for contour specifications.

These stainless steel cut-rifled barrels are made in-house with an absolute commitment to extreme accuracy and quality. They start with double stress-relieved 416R stainless steel, a pre-hardened chromium stainless steel ideally suited for use in precision, match-grade rifle barrels. 416R was specifically designed by engineers in collaboration with barrel makers and rifle manufacturers to provide the consistency, high quality and durability the firearms industry demands.

These barrels are gunsmith ready, meaning that the the barrel is threaded for the receiver but needs to be chambered in the desired cartridge by a qualified gunsmith.

Benchmark Barrels uses only the highest quality 416R and 4140R carbon steel in the production of our product. This ensures that our barrel is the finest you can put on your rifle.

All barrels are individually double hand lapped to a true consistent bore. The manufacturing process also includes double stress relieving and quality control inspection utilizing proprietary methods along with the most accurate industry techniques available. 

We also stock barrels fluted to a specific (installation) length in the popular #4 sporter contour.

When PROOF Research® joined with Lawrence Barrels in 2012 they acquired 15 years of experience in manufacturing precision steel barrels. These stainless steel cut-rifled barrels are made in-house with an absolute commitment to extreme accuracy and quality. They start with double stress-relieved 416R stainless steel, a pre-hardened chromium stainless steel ideally suited for use in precision, match-grade rifle barrels. 416R was specifically designed by engineers in collaboration with barrel makers and rifle manufacturers to provide the consistency, high quality and durability the firearms industry demands.

They are shipped ready to be assembled onto your Ruger Precision™ Rifle by a qualified individual. The barrel will come pre-chambered in the specified caliber, threaded for the receiver and threaded at the muzzle for a supressor or brake.
