OP, if push comes to shove, you can make up a very sturdy scope mount with a piece of angle aluminum or iron.
Use the ejector screw hole as a mount, and add a set screw to the angle iron over the top bridge to get proper elevation, and another on the side to hold it true and you're good to go.
Purple posted a pic of one he had done for one of his rifles.
I've done a few and you don't need much in the way of tools.
If you have to get "someone else" to do it, cost is prohibitive. The S&K mounts work very well.
The monte carlo stock riser on your rifle was purpose designed to use the original OEM sights, that's why it's to low.
If you're handy with wood work, adding an adjustable cheek riser isn't difficult and won't deter any value from your rifle. You can even utilize the present riser on your butt.
