DuraSight has combined innovative design with outstanding heavy-duty materials to give you the best value in rings and bases on the market today. Making tack-driving accuracy available to everyone, the Dead-On one-piece system is the fastest way to mount optics on your CVA muzzleloader. The one-piece system also means there are fewer adjustments that can affect accuracy. The molded Z2 Alloy ensures better ring alignment to grip your scope tighter, with less stress on the scope tube.
