Fierce Firearms 308 Caliber Rifle, 22" Barrel, 1:9 Twist, 5/8"-24 TPI

The Fierce Firearms 308 caliber rifle with 22" barrel is a versatile centerfire platform built for hunters and long-range shooters who demand reliability and precision. This factory barrel comes ready to drop into a compatible Fierce Firearms action, offering a proven 1:9 twist rate that stabilizes a wide range of .308 Winchester and 7.62×51 NATO ammunition weights. Whether you're building a hunting rifle for game at distance or assembling a precision target setup, this barrel delivers the accuracy potential Fierce is known for without the premium cost of a complete rifle purchase.

The 22" length strikes a practical balance: long enough to generate solid velocity and sight radius for accurate shooting, yet short enough to handle comfortably in brush and from vehicles without excessive weight or muzzle blast. The 1:9 twist is a sweet spot for .308—it'll stabilize everything from 155-grain match rounds to heavier hunting bullets, giving you flexibility in load selection and bullet choice. The 5/8"-24 TPI muzzle threading is the modern standard for .308 suppressors and brakes, so you can thread on a can for subsonic hunting, add a muzzle brake to tame recoil on the bench, or leave it clean for classic iron or optic setups.

This is the barrel only—it's designed for shooters who already have a Fierce action or are building a custom rig from components. If you're swapping barrels, rebarreling a worn rifle, or assembling a rifle from a barreled action kit, verify that your action is compatible with Fierce barrel specs before purchase. Proper barrel installation should be done by a gunsmith with the correct headspace tools and torque specs.
