Christensen Arms Pre Fit Cf/Ss Barrel 18 Thread 308

The Christensen Arms Pre Fit CF/SS Barrel in .308 Winchester with 18-inch threading gives you a purpose-built option for hunters and shooters who want a factory-quality barrel without the wait or custom gunsmith work. Built as a drop-in replacement for Remington 700 actions, this pre-fit barrel combines carbon-fiber construction with a stainless steel core to deliver a balance of durability, rigidity, and manageable weight. Whether you're assembling a hunting rifle or upgrading an existing build, a .308 pre-fit barrel saves time and money compared to custom barrel fitting and headspace reaming.

Christensen Arms button-rifles this barrel from 416R stainless steel for consistent internal dimensions and accuracy potential. The CF/SS construction—carbon fiber exterior wrapped around that stainless core—resists corrosion while keeping overall weight down compared to traditional all-steel barrels. An 18-inch bore length strikes a practical compromise for hunting rigs that need to move through timber or brush without sacrificing .308 ballistics. The 18 TPI threading accepts common muzzle devices, and each barrel ships with a muzzle end thread protector to keep those threads clean until you install a brake, suppressor, or flash hider.

This barrel comes in two profile choices: Sporter and Target. Both start at 1.20 inches in diameter and taper to .920 at the muzzle, but they taper differently. The Sporter profile tapers quickly and runs lighter for hunting carry, while the Target profile tapers gradually for extra stiffness, making it better suited to bench shooting and long-range work. Estimated weight is 2 to 2.9 pounds depending on profile.

Frequently Asked Questions

What actions does this pre-fit barrel work with?

This barrel is machined as a drop-in fit for Remington 700 actions. If you have a different platform, you'll need to check the manufacturer's compatibility chart or consult a gunsmith.

What's the difference between the Sporter and Target profiles?

Both profiles start and finish at the same diameters, but the Sporter tapers quickly from breach to muzzle, keeping weight low for hunting. The Target profile tapers more gradually, adding stiffness and thermal mass for better precision at distance and in high-round-count shooting sessions.

Does this barrel come ready to use?

As a pre-fit barrel, it's machined to drop into a Remington 700 action without custom fitting. You will still need to have it properly installed and headspaced by a gunsmith if you are not experienced with barrel installation. It ships with a muzzle thread protector to keep the threads clean.

What muzzle devices can I attach?

The barrel has 18 TPI threading, which is standard for most .308 muzzle brakes, flash hiders, and suppressors. Make sure any device you choose is chambered or rated for .308 and 18 TPI.
