Making Accuracy Commonplace

Industry Leading Rifle Barrels

High Quality Design & Manufacturing

When PROOF Research was formed in 2012, our vision was both simple and extraordinary. Our truly innovative founders envisioned a company that would apply advanced science, new technologies, aerospace-grade materials and manufacturing excellence to produce a new class of products that would truly revolutionize the firearms industry.

Performance and Excellence

Our barrels, both carbon fiber and steel, exemplify our founders’ relentless pursuit of excellence. Whatever your preference is, you can expect the finest rifle barrel in the industry.

Available are bolt-action barrel blanks that will arrive ready for thread and chamber by your gunsmith, AR-style barrels that come threaded and chambered and bolt action Pre-Fit barrels that come threaded and chambered.

Carbon Fiber Barrels

for Bolt-Action and Semi-Auto Rifles


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.

Up to 64% lighter than traditional steel barrels of similar contour
Match-grade accuracy
Improved heat dissipation for cooler and longer lasting barrels
No point-of-impact shift during high-volume fire
Reduced harmonic barrel vibration
Unprecedented durability

Steel Barrels

for Bolt-Action and Semi-Auto Rifles


We make our steel barrels in-house with the exact same commitment to quality and repeatability as employ on our carbon fiber barrels. The drilling, rifling, and lapping process is identical to our composite barrels.  We start with the same steel as we use in the carbon fiber barrels.  It is a double stress-relieved 416R stainless steel, a pre-hardened chromium stainless steel that was specifically designed by engineers in collaboration with rifle barrel makers to provide the consistent, high quality and durability the firearms industry demands. 

  • Excellent machinability for gun drilling and reaming, plus exceptional polishability for uniform lapping
  • A homogeneous microstructure which responds to heat treatment providing a uniform hardness along the length of the barrel
  • An optimum combination of high tensile strength along with requisite toughness to withstand extreme chamber pressures encountered during firing
  • Excellent erosion wear characteristics and corrosion resistance
