In need of ring height for Weatherby Terramark

[BLC3128]

New to the forum! I decided to move on up in the optics world and replace my Vortex Viper HST with a Nightforce SHV 5x20x56 and I will be mounting it to a Weatherby Mark V Terramark (300 WBY). The Terramark currently has a Kenn Farrell 20 MOA base installed (this is the heavy duty or "force" model).

What size rings will allow me to mount the scope as low as possible? I prefer to keep the base and use Ken Farrell rings. Another factor is that I would like to install scope caps, but I do not mind modifying the caps if it is a tight fit.

This is the data from Kenn Farrell's website.

RING HEIGHTS
LOW = 0.735"
STANDARD = 0.835"
MEDIUM = 0.935"
HIGH = 1.035"
EX-HIGH = 1.235"

Thanks in advance,

Brandon.

With a 56mm objective, you might possibly get by with the high rings. If not, the extra high will have to be used.

This is how it looked with Vortex Viper rings in medium (.97 inches). The scope has a 44mm objective with a thick scope cap (Vortex defenders). I believe I can go lower, possibly with Ken Farrell standard (.835 inches). Any thoughts?

You can get the measurements for each scope's objective from the manufacturer's website. Vortex scope: 2.03", NF scope: 65mm (2.56"). So the new scope will stick down 0.26" further. Measure how much clearance you have with the Vortex and you can calculate ring height for the NF scope.
