A Christensen Arms 450 Bushmaster 20" 1-16 twist sporter contour carbon-fiber barrel is purpose-built for shooters who want match-grade accuracy in a lightweight, thermally stable platform. This barrel combines aerospace-derived precision engineering with proprietary carbon-fiber construction, making it an ideal upgrade for Remington 700-compatible builds or custom rifle projects where rigidity and repeatability matter. Whether you're building a hunting rifle, tinkering with a range gun, or just refreshing your action with a fresh tube, this .450 Bushmaster chambering delivers the velocity and energy needed for medium to large game.
The barrel itself is a match-grade 416R stainless steel bore and chamber, hand-lapped for consistency and held to extremely tight tolerances (±.0001"). That precision is wrapped in a carbon-fiber shell using Christensen Arms' layered design—a process borrowed from aerospace manufacturing that reduces weight while eliminating the heat buildup and poi shifts that plague traditional steel barrels. The sporter contour strikes a practical balance between weight and rigidity, keeping the rifle balanced and handy without sacrificing the stiffness needed for groups.
The 1-16 twist rate is optimized for .450 Bushmaster projectiles, ensuring stable flight across the range of bullet weights commonly fired in the cartridge. This is a barrel component only—you'll need to have it properly installed and headspaced by a competent gunsmith, and you'll confirm it's a correct fit for your specific receiver before ordering.
| Caliber | .450 Bushmaster |
| Length | 20 inches |
| Twist Rate | 1-16 |
| Contour | Sporter |
| Material | Carbon-fiber wrapped 416R stainless steel |
| Chamber Tolerance | ±.0001" |
| Platform | Remington 700 compatible |
This barrel is Rem 700 compatible, meaning it's designed to work with standard Rem 700 actions. However, a competent gunsmith must install it, properly headspace it to your specific receiver, and ensure correct fit and function. Do not attempt self-installation without professional help.
This is a barrel component only. Installation, headspacing, and integration with your action, stock, and optics are your responsibility. You will need a qualified gunsmith to complete the work.
The 1-16 twist rate is matched to stabilize the projectile weights and designs most commonly loaded for .450 Bushmaster. Proper twist ensures accurate, consistent bullet flight and helps you achieve the accuracy the match-grade bore and hand-lapping are designed to deliver.
Carbon-fiber construction, as used in this Christensen Arms barrel, significantly reduces weight compared to solid steel, making the rifle easier to handle and carry. The layered design also dissipates heat more effectively, which means less thermal expansion and shift in point of impact during rapid shooting or long sessions—a real advantage for both hunting and range work.
