CVA® Anti-Seize Grease helps to prevent breech plug or nipple threading from seizing. The CVA™ Breech Plug and Nipple Grease is formulated to withstand the intense heat created during powder ignition. Simply apply a small amount of grease to your breech plug or nipple after cleaning, to ensure that your barrel and plugs will not weld during ignition. A great way to keep your muzzleloader in great condition with little effort!
