Proof Research 308 Win Terminus Pre-Fit Steel Barrel makes it easy to upgrade your current rifle. The steel pre-fit barrels for the Terminus Apollo, Zeus and Kratos actions come chambered and threaded for an easy install.

Manufactured from high-quality 416R stainless steel, the barrel provides excellent strength, corrosion resistance, and barrel life, making it well suited for the sustained pressures and heat associated with .308 Winchester.

Common configurations feature a 1:10 twist rate to stabilize a wide range of .308 bullet weights, along with 5/8-24 muzzle threading for compatibility with suppressors and muzzle devices. Known for consistent machining, smooth internal finishes, and reliable accuracy, this steel pre-fit barrel is favored by precision shooters who want a durable, traditional steel option with the flexibility to match their rifle setup and shooting discipline.
