Thompson/Center | Prohunter Rifle Barrel | 300 Win Mag | Stainless Steel

Thompson/Center's break‑open interchangeable‑barrel system means one frame can run rifle, pistol, shotgun, or muzzleloader barrels across a huge range of calibers and gauges -⁠- swap the barrel with no gunsmithing or special tools, and the design is genuinely foolproof, since it simply won't close if the barrel isn't seated correctly. This ProHunter centerfire rifle barrel is button‑rifled with 5R hammer‑forged rifling, brush‑honed, and finished with a match‑grade crown, drilled and tapped for scope mounts with no additional gunsmithing needed. Every barrel is factory test‑fired at 100 yards to verify real accuracy before it ships, available in stainless or blued finishes across 20 and 26‑inch lengths depending on caliber -⁠- genuine one‑gun‑many‑calibers versatility, not a single‑purpose rifle.
