Headquartered in Northwest Montana, PROOF Research is known for redefining the status quo by creating state-of-the-art carbon fiber rifle barrels and complete rifle systems that outperform everything else on the market. PROOF uses a patented manufacturing process that utilizes aircraft-grade carbon fiber in conjunction with high-temp aerospace resins to deliver lightweight performance barrels, receivers, firearm platforms, parts, and accessories. Their barrels and rifles are lighter, stronger, and more accurate than the finest match-grade steel and have quickly gained a reputation among backcountry hunters, precision rifle competitors, and military operators for ruggedness, durability, and extreme accuracy.
