Thompson Center Arms Llc 0040R Tca Impact Breech Plug

The Thompson Center Arms 0040R Impact Breech Plug is a stainless steel breech plug engineered specifically for Thompson/Center muzzleloading rifles. If you're running a TC muzzleloader and need a replacement or upgrade breech plug, this OEM part delivers the precision fit and material quality you expect from the manufacturer. Whether you're a dedicated black powder hunter who shoots year-round or a seasonal rifleman who depends on reliable ignition, a quality breech plug is essential—it's where the hammer strikes and where pressure seals during the shot.

Stainless steel construction resists corrosion from black powder residue and moisture, a real advantage if you hunt in wet conditions or don't get to clean immediately after a range session. The plug is designed to work with Thompson/Center's Impact platform, ensuring proper headspace and alignment for consistent ignition and safe operation.

Replacement and maintenance breech plugs are often overlooked until they're needed, but keeping a spare on hand or upgrading to fresh hardware is smart preventive maintenance. A properly seated, clean breech plug ensures reliable firing pin strikes and helps you avoid misfires in the field when it matters most.
