How do you know what height of the mounting rings to use? or is it just trial and error?
Have a Ruger American Gen 2 and putting a Sig Sierra3 scope on it; however, when looking at scope rings it asked what height, Low, Medium, or High.
Sportsmans Warehouse has an online tool that you can use that will let you know what the right height is.
I’ve also had success just emailing the company that makes the mounts/rings and telling them what I’m looking to do and they’ll let me know what works best.

Thanks, I check it out.
Here’s the link to the Sportsman’s Warehouse “Ring and Base Finder” page:
Unfortunately, they don’t have the Gen II rifle listed. Guess I’ll just start with medium and go from there.
You can always check with ruger, or even perhaps your local gun store if you have one that you trust. More often than not when a company upgrades a rifle that does not change the scope mounting system at all. If it did, that would just create so many hassles regarding what rifle do you have, people buying the wrong mounts, etc etc. Then you could just use whatever it says for Gen 1.
That being said, if it’s got a picatinny rail mediums typically do real well unless it’s a massive scope like a 56 mm. If it’s a smaller scope like less than 40 you may even get by with low rings
Yes it has a pic rail. but the Gen II has a different comb setup.
Rule of thumb: up to about 44mm objective you can usually get away with low rings. Over that, such as 50mm, and you’re looking at medium, and when you get up to 56mm=high

Andrew,
This is what I do, since I have not mounted a scope yet.
I take a scope, in the case of my Ruger Gen II, an Arken Gen II 6-24/50 to my gunsmith at my FFL store and he adds the Rings and then zeros the scope to a 100 yards. I looked, and it seems, he likes Vortex brand b/c that is what he uses on all my rifles he has mounted a scope for. He used a couple of Vortex, “Low” height (usually 1" height), on mine. For me “Low” height seems to work best. And I did try the link at Sportsman, that is pretty cool. I tried it out on a couple of different rifles to see what it recommends. It is good to know. Thanks.
If you have the scope and rifle you can use spacers (like stacked quarters or something similar) to measure. Without knowing the exact spacing of the scope to barrel for your length of pull its impossible to give a precise answer.
Thanks for the tip. I think I will try it and compare different ring heights on my rifles.
