Swarovski Z6 5-30x50

[Newbie_hntr]

Hey roksliders I’m pretty new to this forum and have a question. So I just got a crazy deal on this scope it’s a Z6 5-30x50. I wanted it in the 3-18x50 configuration, but the guy who sold it to me told me he couldn’t get one for a while, and would not be able to give me the deal he gave me on this one. It’s going on a Weatherby Mark V 300wby mag. I currently have an older habicht 2.5-10x42 on it. It’s got the 30mm tube but not sure exactly what model. Was wondering what you guys would do;
A leave it alone
B swap them out or
C trade the scope for a 3-18x
Thanks for anyone’s help in advance
