PROOF Research, Inc. is a defense and space manufacturing company based in Columbia Falls, Montana. It produces lightweight, high-precision rifle barrels by wrapping in-house, reduced-profile 416R stainless steel blanks with aerospace-grade carbon fiber and a proprietary resin. The resulting composite barrels are described as stronger and lighter than traditional steel while preserving accuracy in challenging environments. The company targets precision firearms applications and related defense markets, offering solutions that address the need for manageability without sacrificing performance. In May 2026, PROOF Research announced the PROOF Exponential Twist rifling as well as shorter barrel configurations for Elevation 2.0 and Elevation MTR 2.0, reflecting ongoing product development.
