Proof Research 375 Bolt Action Carbon Fiber Barrel

The Proof Research 375 Bolt Action Carbon Fiber Barrel are much lighter, more durable, and accurate than traditional barrels. Proof Research make these Rifle Barrels starting with full profile, match grade 416R stainless steel barrel blanks that are then turned down to a significantly reduce its weight. The Proof Research barrels are then wrapped with high strength, aerospace grade carbon fiber. 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. They’re not just lighter, they’re better.
