Thompson/Center | Prohunter XT Barrel | .45 Caliber | 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 XT muzzleloader barrel includes the Speed Breech 3 hand‑removable, threaded breech plug -⁠- genuinely faster field cleaning than a fixed breech design -⁠- with a 1:24 twist tuned for stabilizing sabot and conical projectiles. Available in .45 and .50 caliber across 20 and 28‑inch lengths in blued, stainless, or Nitride finishes, drilled and tapped for a scope with no additional gunsmithing needed.
