Thompson Center
The Thompson Center ProHunter rifle barrel in .300 Win Mag gives you the flexibility to transform your single-shot or break-action platform into a dedicated magnum hunting rifle. If you already own a Thompson Center ProHunter or Encore frame, this 26-inch barrel swap lets you chamber one of the most effective long-range hunting cartridges without buying a whole new gun. The .300 Win Mag is proven medicine for elk, moose, and other big game at distance, and this barrel delivers the velocity and accuracy that caliber is known for.
Single-shot rifles built on interchangeable barrel systems make sense for hunters who want versatility without the bulk of carrying multiple firearms. Swap barrels, reconfigure your setup, and you're ready for a different hunt. This ProHunter barrel comes finished in blue and is ready to drop into a compatible frame—no gunsmithing required. It's a practical upgrade for shooters already invested in the Thompson Center system.
Before you order, confirm your rifle's frame is compatible with ProHunter or Encore barrels. This is a barrel only and does not include a firearm, stocks, or other components. If you're building out a modular hunting rig or adding a magnum option to an existing gun, this is a straightforward way to do it.
