You can use Optilock system on Bergara B14 only if you have a picatinny rail. Optilock bases for Bergara rifles does not exist.
If you would like to use one scope on two different rifles then we would recommend Dentler system. With this system you will be able to use the same scope on two different rifles without loosing a zero.
More about Dentler system you can see at the link below:

On one of the rifles you need to have a BASIS VARIO base, on the second you can have BASIS base.
On the links below you can find all bases for both rifles.
