Thompson Center Arms 0020R Encore ProHunter FX Speed Breech 3 50 Cal Breech Plug - Silver Steel

The Thompson Center Arms 0020R is the Speed Breech 3 replacement breech plug designed for the Encore ProHunter FX muzzleloader platform. Machined from steel with a clean silver finish, this breech plug is purpose-built for 50 caliber muzzleloading rifles chambered in the 209x50 black powder configuration.

As part of the modular Encore system, the breech plug is the critical component that seals the chamber against the barrel during firing. The Speed Breech 3 design streamlines the loading process, making it faster and easier to seat a projectile and priming charge compared to earlier breech generations. Its solid steel construction is built to handle the pressures of black powder ignition and repeated cleaning cycles, giving muzzleloader shooters a reliable factory-spec replacement.

This genuine Thompson Center Arms component installs directly into any compatible Encore ProHunter FX rifle, restoring safe and reliable function when an existing breech plug has worn, been damaged, or needs to be swapped for routine maintenance. Whether you keep a working muzzleloader in the field or are building out a custom Encore configuration, the 0020R Speed Breech 3 is the correct factory part for the job.
