Swarovski BTF Ballistic Turret

The Ballistic Turret Flex (BTF) can be used as a top or side turret on all Z8i model scopes. The BTF simply clicks on and off the turret and is supplied with a graduated ring showing the number of clicks and a right/left graduated windage ring, or you can use the BTF with the supplied marking rings which you can set at your desired distances (using the Swarovski ballistics program). The lock mechanism prevents your zero being moved inadvertently.
