You may be pioneering putting a 56mm objective scope on a sporter.
You can definitely come down some, but if the bolt will not operate, you are kind of hosed. If you run rings that high, being it is a sporter stock and not the monte carlo version like some or all Browning made ones had, I wonder if you are going to end up with a wonky cheek weld.
You can't just slide a scope forward or back and expect it to work anywhere, sure you know this, but by first pic, I am not sure the scope is back far enough.
Grab one, or 2 of your rifles and measure the distance from the back of the butt plate to the scope eyepiece, you will find they may be extremely close in distance. Check the distance here. I am wondering if that front base being extended may not bite you.
If it was my rifle, and I needed to run that optic, I would opt for a picatinny rail from EGW and start there, my .02
