The Muzzleloader Capper & Extractor Tool is designed for all muzzleloaders with a 209 primer ignition. The #209 Capper Tool allows for easy capping and removal of all #209 primers. The capper/decapper tool is made of hardened steel and works on any brand of inline muzzleloader. DESIGN CORRECTION UPDATE - The old model of this capper tool did not have a proper capper end slot capable of holding a 209 primer. This design flaw has been corrected and all new Capper/Extractor tools starting from May 2022 now have a capper end slot that will hold a 209 primer.
