Putting the finishing touches on my first bolt action build and the last thing I need is something to mount the Mark 5 HD on the seekins BA in KRG chassis. The two questions I have are what height and whether I should use rings or a one piece mount. What are the considerations when choosing the mounts? I know I want to keep height over bore as low as possible but i one day might want to add a clip on thermal to cowitness. Any help would be appreciated
