The Breech Plug Master Maintenance Kit is a comprehensive toolset for maintaining modern in-line muzzleloaders. Engineered for precision and ease of use, this kit provides all the tools necessary for removing and cleaning breech plugs across most muzzleloader brands. Every tool in the kit is purpose-built to address the unique challenges of muzzleloader maintenance, ensuring that fouling, debris and residue are effectively removed to keep your firearm performing at its best. At the core of the kit is the Breech Plug 4-in-1 Scraper, a compact, multi-functional tool designed to clean breech plugs thoroughly and efficiently. It features interchangeable components for cleaning tapered surfaces, removing fouling from hard-to-reach areas and clearing flash holes without requiring breech plug removal. The scraper’s push-button mechanism allows for quick deployment of each tool, making it both versatile and practical for use at the bench or in the field. This innovative design ensures that every aspect of breech plug cleaning is covered with minimal effort. The kit also includes a double-ended spanner wrench and a set of specialized sockets, including 11mm, 12mm, slotted & oval breech sockets. These tools are ideal for loosening or tightening breech plugs securely, even in stubborn or fouled conditions. Additionally, the ¼" socket breaker bar and its extensions provide extra leverage for removing tightly seated plugs. With durable construction and compatibility across a wide range of muzzleloader models, these tools are essential for ensuring proper breech plug function and preventing damage during maintenance. The kit incorporates Breech Thread Brushes, which are specifically designed to clean threads and remove fouling from breech areas with precision. The brushes are complemented by cleaning rod extensions, allowing for deeper and more thorough cleaning of the breech and barrel. All tools are organized within a weather-resistant case, providing compact and secure storage
