CVA Blackhorn Breech Plug for Nitride Guns - 209 Primer - The CVA Blackhorn QR Breech Plug for Nitride muzzleloaders is specifically designed for use with Blackhorn or other loose powder muzzleloading propellants. Nothing affects the performance of your muzzleloader more than a clean breech plug for consistent ignition and better overall accuracy. While the Nitride process is not done on these breech plugs, they do feature a 'black oxide' coating, which protects from rust and corrosion, while still giving the same appearance as the Nitride barrels. This black oxide coated, stainless steel replacement breech plug, is designed to work with all CVA Accura V2, Optima and Wolf models, 2010 or newer. This plug is optimal for whatever type of propellant you choose to use, either loose or pelletized. The CVA 209 breech plug allows the flash-hole to remain debris-free after repeated shots with fine, loose powder propellants. You no longer need to continually clean out the flash hole after each shot.
