You’re new to doubles so you’re making some missteps here.
First, you do not buy the scope and then the mounts. You buy the mounts and then the scope on a double rifle.
Trust me, this is very important advice. To avoid yourself untold troubles, you must have EAW Pivot bases installed on your rifle. This mounting system is the only arrangement that allows you to change scopes, although changing them is still expensive.
Regarding your scope. The scope is too big and it may or may not fit. You’ll prefer a straight tube scope whether rail mount style or standard 30mm rings.
To explain to you why the things I said above are true and accurate statements would require me to write you a ten page document, but I assure you they are the best path forward at the lowest cost and most reliability while retaining the ability to change or add scopes in the future.
Any scope with a bell is going to provide you a bad sight picture and increased recoil over a straight tube scope. The comb was not designed to handle a higher sight picture than the iron sights.
Can your scope be made to work? Yes. But you will dearly regret it. The installation will result in mounts located in the wrong spots for use with straight tube scopes in the future. The recoil will be severe. When you’re disappointed with the optic or it breaks, you will be forced to throw away the barrels or have a new quarter rib made and the gun re-regulated to start over the correct way.
P.S. - The scope mounts above are the wrong type. As you said, those are for a Heym SR30. You underestimate the cost and complexity of putting scopes and mounts on a double rifle. You cannot buy parts here and there, you need a specialist to do it all for you. The cost for mounts and scope that are correct will be relatively similar to the price of the rifle.
