At PROOF Research we're proving that 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. Our lightweight barrels run as hard as any steel barrel while reducing harmonic barrel vibration and improving heat dissipation resulting in virtually no point-of-impact shift during high-volume strings of fire.
They’re not just lighter—they’re better.
Material Properties (fiber/matrix)
Minimizing POI Shift
Research is redefining the firearms industry by engineering carbon fiber barrels for ARs and bolt-action rifles that outperform everything else on the market. Carbon fiber is seven times stronger than steel and is nearly impervious to weather, nicks, scratches, or dings. Our carbon fiber barrels begin as full-profile 416R stainless steel barrel blanks that we manufacture in-house. The blanks are then turned down to a reduced profile everywhere but the shank, muzzle, and gas block journal (where applicable). This reduced profile is then wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin. We then cure the newly applied carbon fiber. We then cure the newly applied carbon fiber and PBA. Once hardened, the barrel is finished to its final sleek profile, single point cut-rifled, hand lapped and borescope inspected. The end result is the finest rifle barrel on the planet.
Up to a 64% reduction in weight over traditional steel barrels (depending on length)
Reduced harmonic barrel vibration
Better heat dissipation resulting in more accurate and longer lasting barrels
When we acquired a boutique barrel manufacturer in 2012 we inherited 15 years of experience in manufacturing precision steel barrels. We make our steel barrels in-house with an absolute commitment to extreme accuracy and quality. We 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.
416R is our stainless steel of choice because it has the following characteristics:
• Excellent machinability for gun drilling and reaming, plus exceptional polishability
for uniform lapping—a must for bore accuracy.
• A homogeneous microstructure which responds to heat treatment providing a
uniform hardness along the length of the bar, necessary for accurate rifling to
precise groove dimensions.
