The Proof Research Model 100950 is a .284 caliber, 26-inch bolt-action carbon fiber barrel with a 1:8.4 twist rate and Sendero contour, weighing 3 lbs 4 oz. This barrel features 416R stainless steel wrapped in carbon fiber, with match-grade accuracy, improved heat dissipation for cooler and longer-lasting barrels, no point-of-impact shift during high-volume fire, and reduced harmonic barrel vibration.
This carbon fiber barrel is up to 64% lighter than traditional steel barrels of similar contour and provides extreme temperature resistance that improves heat dissipation for cooler, longer-lasting barrels. The barrel is wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin, with aerospace-grade carbon fiber having a specific strength up to 30 times that of stainless steel and a specific stiffness up to 7 times greater than steel. The carbon fibers diffuse heat along the length of the barrel and move heat very effectively through the barrel wall, resulting in barrels that cool faster, maintain accuracy over longer sessions of fire, and live longer.
The barrel features a 2.5-inch breech length and 1.20-inch shank diameter, and arrives ready for thread and chamber by your gunsmith. The 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.
