Fierce Firearms 24" .284 7mm Barrel - 1:8 Twist (Model 2841824)

The Fierce Firearms 24" .284 7mm barrel with 1:8 twist is a precision replacement barrel built for AR-15 shooters who want to chamber a potent intermediate cartridge without a complete platform rebuild. The .284 (7mm) caliber splits the difference between standard 5.56 NATO and full-power rifle rounds, delivering effective range and energy for hunting and precision shooting while maintaining AR ergonomics and controls. This 24-inch barrel gives you the velocity and sight radius that long-range applications demand, and the 1:8 twist rate is engineered to stabilize the bullet weights commonly used in .284 Winchester and similar 7mm handloads.

Swapping barrels on an AR-15 is straightforward for anyone with basic gunsmithing tools and knowledge. This barrel is a direct fit for standard AR-15 upper receivers, so if you already run an AR platform, you can quickly convert to .284 performance without investing in an entirely new rifle. Whether you're building a dedicated long-range rig, a hunting carbine, or exploring what this underrated cartridge can do, a quality barrel like this one is the foundation of accuracy and reliability.

Fierce Firearms builds barrels with the precision and attention to detail that serious shooters expect. This 24-inch, 1:8 twist configuration represents a thoughtful balance between velocity, sight radius, and handling for an intermediate-caliber AR platform. Check your upper receiver compatibility and twist-rate ballistics for your intended ammunition before purchase.
