The Sig Sauer Whiskey3 4-12x40mm Rifle Scope uses a 1" tube, and you would need rings that accommodate 1" tubes. As for the height, it can depend on the rifle you intend to put to scope on. For the AR15 platform, I'd recommend the highest rings available. For a bolt gun, or 10/22, anything else, I'd recommend low to mid height rings. You can find out more about the height you would need by using this how to guide linked below:
