Thompson Center 9021R T17 BREECH PLUG CLEANER
$9.75
If you shoot a Thompson Center muzzleloader, you know that black powder and substitutes like Triple Seven leave stubborn residue in the breech plug's flash hole—the critical passage that ignites your charge. That's where the Thompson Center T17 Breech Plug Cleaner comes in. This purpose-built solvent penetrates and dissolves fouling in the flash hole without requiring brushing or scrubbing, saving you time during cleanup and helping restore consistent ignition shot after shot.
Muzzleloader maintenance matters. Fouling buildup in the breech plug doesn't just make cleaning harder; it can affect reliability and accuracy. The T17 is formulated specifically to handle black powder and black powder substitute residue, so you're using the right tool for the job instead of a general-purpose gun cleaner that wasn't designed for this application.
Whether you're cleaning after a day at the range or doing post-season maintenance on a muzzleloader you rely on for hunting, this cleaner takes the guesswork and elbow grease out of breech plug maintenance. No soaking, no scrubbing, no special equipment—just apply and let the chemistry work.
