Swarovski BTF Ballistic Turret Flex
The clever ballistic turret flex (BTF) from Swarovski is a removable ballistic turret that can be used on either (or both) the elevation or windage turrets of any of the new innovative Z8i rifle scopes. It can be integrated with any of the available reticules and can be configured separately.
It ensures the ability to have different set zeros at desired distances. Very easy to fit (without any sort of tool), the BTF turret uses a lock mechanism to prevent unintentional turning.
