Designed to withstand the demands of super magnum charges in Paramount rifles, this improved breech plug eliminates the durability issues found in earlier models. Engineered specifically for use with large rifle primers, it ensures consistent ignition and improved accuracy with every shot. A clean breech plug is essential for peak muzzleloader performance, and the VariFlame design helps keep the flash-hole free of debris, even after repeated shots with fine, loose powder propellants. Say goodbye to constant flash-hole cleaning between shots and enjoy a more seamless shooting experience. Compatible with all CVA Paramount muzzleloader rifles, this breech plug is optimized for use with both loose and pelletized propellants. The patented VariFlame primer adapters allow reliable ignition using large rifle primers, giving shooters superior reliability and precision in every shot.
