If you have target turrets on your scope from the factory, I think they can make you a custom turret. Otherwise, it has to go back to the factory and be refitted. I have two conquests. One with the turrets and one without. I would say just by looking at the way that they are adjusted, that the one without the turrets would have to be retrofitted with turrets to be able to accept custom turrets. Don't take my comments as gospel, but it does seem that I remember reading that somewhere and again, just observation of the differences between the scopes.
As far as liking the scopes, I really like them. They are very clear with good contrast. A hunting buddy and I have come to agree that they are the best value on the market. If they would make it a 30mm tube, give it a little more elevation travel and a turret that has about 10 MOA per revolution compared to 18, I might not own anything else. But as it is, I do. In a nutshell, I really like them.
