Proof Research 264 Win Mag 24" Carbon Fiber Bolt Action Barrel Blank - 416R Stainless Steel, Sendero Light Contour
Proof Research
The Proof Research 264 Win Mag barrel blank delivers long-range accuracy and durability without the weight penalty of traditional steel. Built from a combination of 416R stainless steel and carbon fiber, this 26-inch blank in Sendero contour is engineered for shooters who demand precision, heat management, and reliability on everything from competitive matches to backcountry hunts. Whether you're building a custom rifle or replacing a worn barrel, this 1:8 twist rate supports the full spectrum of modern 264 Win Mag ammunition.
Carbon fiber construction cuts barrel weight by up to 64 percent compared to steel barrels of equivalent profile, a significant advantage if you're building a long-range rig that won't wear you down during a full day in the field. That weight savings doesn't sacrifice stiffness or durability—the material excels at dissipating heat, keeping your barrel cooler during high-volume shooting strings and extending barrel life. The combination of reduced mass and superior thermal management also minimizes harmonic vibration, a key factor in match-grade accuracy and point-of-impact stability even when conditions demand back-to-back shots.
This is a blank barrel, meaning it arrives ready for threading, headspacing, and installation by a qualified gunsmith—not a complete, ready-to-mount assembly. Pair it with your preferred action, stock, and optics to complete a 264 Win Mag build tailored to your shooting discipline and field conditions.

This barrel is up to 64% lighter than traditional steel barrels of similar Sendero contour, a meaningful reduction for a long-range or hunting rifle where every ounce counts.
No. The carbon fiber construction is engineered to reduce harmonic vibration and improve heat dissipation, both of which support match-grade accuracy and point-of-impact stability. There is no point-of-impact shift during high-volume fire.
