A custom Ballistix turret is a user-installed replacement for the stock elevation turret on a rifle scope. It replaces the indicators on the factory turret (clicks, MOA, MILRAD etc.) with precise yardage markers. Simply range find your target, dial in your turret, breathe and shoot. The Ballistix tool itself helps customers design and customize a custom yardage turret using their exact ammunition, muzzle velocity, environmental factors and scope to ensure the customer is dialed-in and dead-on every time.
